    • 摘要: In setting of the cross connecting line in dedicated passenger railway line,No.42 large size turnout is selected for the main line and the setting principle of Balise group for large size turnout is analyzed in the light of engineering practices. When the over speed limit of the fixed speed limit is set smaller than that required for the siding of the departure section,the EMU is subjected to over speed risks. Through the analysis and study of the setting of the large size turnout Balise group and the principle of the message transmission,this paper calculates the length of routing,and theoretically analyzes whether there are occurrences of over speed of the EMU in special scenes. The results show that when the side-access signal with large size turnout is open to the USU and the side-way connection is made,and at the same time,the permissible length of routing exceeds the braking distance range,and there is no temporary speed limit less than that of the lateral allowable speed for large size turnout,the train control center can send large size turnout data packages; meanwhile,in the departure section,when there is a fixed speed limit in the range of braking distance,which is less than the lateral allowable speed for large size turnout,EMU train will be in operation without over speed.%客运专线铁路在设置跨线联络线时,正线道岔选用1/42大号码道岔后,需结合工程实际研究大号码道岔应答器组的设置原则,同时分析在大号码道岔离去区段设置有小于道岔侧线允许过岔速度的固定限速时,动车组列车存在超速的风险.通过分析研究大号码道岔应答器组的设置及报文发送原则,计算进路行车许可长度,理论分析特殊场景下动车组接发车是否存在超速的应用举例,研究结果表明: 对于具备大号码道岔的侧向进路,当侧向接车时进站信号机开放USU,且同时满足进路行车许可长度超过制动距离检查范围,侧向进路范围内无低于大号码道岔侧向允许速度的临时限速条件时,列控中心可发送大号码道岔数据包;同时在离去区段制动距离内有低于大号码道岔侧向允许速度的固定限速时,动车组列车运行无超速的可能.

    • 摘要: Based on the subgrade engineering of the new Tongliao to Xinmin North Station of Beijing-Shenyang High Speed Railway,a series of in-house tri-axial tests under the condition of consolidation and non-drainage are carried out to study the stress-strain relationship and the development law of the pore water pressure of the medium dense silty sand with 10%, 15%, 30% and 40% of fine particles. The influences of different fine particle contents on the developing characteristics of pore water pressure of the medium dense silty sand under different confining pressures are demonstrated. The experimental results show that, the stress and strain curve of the medium dense silty sand under the condition of spatial stress tends to show a strong hardening state with the increase of the confining pressure and in a weak hardening state with the increase of the fine article content. Along with the development of shear,the variation of pore water pressure increases firstly and then drops after the peak value is reached. In addition,with the increase of the fine particle content and confining pressure,the peak pore pressure increases and the dissipation rate of pore water pressure decreases showing a trend of delay and greater residual pore pressure; the initial shear modulus is positively correlated to the confining pressure and increases with the increase of confining pressure. Meanwhile, the authenticity and reliability of the above experimental results are proved by using a computer model test base on finite analytical procedure ABAQUS.%依托新建通辽至京沈高铁新民北站铁路路基工程,对细颗粒含量分别为10%、15%、30%和40%的中密状态粉砂开展一系列室内固结不排水三轴试验研究,通过试验研究不同细颗粒含量粉砂在不同围压条件下的应力-应变关系、孔隙水压力的涨消发展模型及初始剪切模量的发展规律,揭示细颗粒含量和围压对中密状态粉砂应力-应变关系、孔压演化特性及初始剪切模量的影响规律.结果表明:空间应力状态下的不同细颗粒含量中密粉砂的应力-应变关系曲线以硬化型为主,符合增长型双曲线模式,且随着围压的增加,应力-应变关系曲线呈现强硬化状态,随着细颗粒含量的增加,应力-应变关系曲线呈现弱硬化状态.孔隙水压力的变化表现为随剪切的发展先经过一段上升过程,达到峰值后又开始下降,且随着细颗粒含量的增加,围压的增大,孔压的峰值越高,孔压消散速度降低,剪切完成后的残余孔压越大.初始剪切模量与围压呈正相关,即随着围压的增大而增大.同时,运用ABAQUS有限元程序建立计算机模型模拟试验,进一步验证上述分析结果的真实性与可靠性.

    • 摘要: The section of DK314+501 ~DK316+800 is a deep cutting slope in Karst Area, which is located between Changsha and Yuping on Changsha-Kunming dedicated passenger line. The main line passes through the undulate terrain with shallow layer clay of weak expansive property. The slope monitoring data obtained are of obvious jumping and mutation, and could hardly be used in slop deformation prediction and slope safety assessment. In order to improve slope monitoring data analysis and application, data preprocessing methods are studied systematically and the methods of interpolation, translation, elimination and smoothing are proposed. Finally, slope monitoring data fitting and displacement prediction are also carried out based on Changsha-Kunming dedicated passenger line. The smoothed and noise-reduced data series of equal time interval are fitted with high order polynomial function, which meets the requirement for short-term forecasting,but insufficient for medium or long term prediction,and the original fitting data should be updated in real-time. The research results could be applied in the automatic monitoring data preprocessing of cutting slop during railway engineering.%长昆客运专线长沙至玉屏段DK314+501~DK316+800为岩溶地段深路堑边坡,线路以挖方通过山包腰部,地形起伏较大,浅层黏土为弱膨胀性.边坡位移监测数据存在明显的跳跃性、突变性特点,难以直接应用于路堑边坡变形发展趋势预测和稳定状态评估.为提高路堑边坡监测数据分析处理水平,挖掘现场监测数据的应用价值,研究路堑边坡监测数据的预处理方法,开展监测数据的等时距插值、平移还原、异常点剔除还原及平滑降噪方法研究,并进行长昆客运专线路堑边坡监测数据的拟合和位移发展趋势预测.平滑降噪后的等时距序列采用高次函数多项式拟合,能够满足短期预测要求,但中长期预测效果较差,拟合数据范围需实时更新,该研究成果为铁路工程路堑边坡自动监测数据的预处理方法提供参考和借鉴.

    • 摘要: When direction schemes is used to allow dedicated passenger railway line to come into and get out of a station,a large number of imply supported box girders with nonstandard line space are required in the bridge design and the issues involved in the design and batch prefabrication of the box girders are urgent to be studied. Based on simply supported box girders with 5.3 m line space in Lianyungang-Zhenjiang railway,this paper introduces the design of girders and focuses on the problems such as lifting and erecting girders due to line space increase in order that the unified design and construction of nonstandard girders and standard girders with 4.6m line space can be realized. The results show that it could meet the usage requirements of simply supported box girders with nonstandard line space to apply modest changes to existing design drawings and construction equipment.%客运专线铁路采用方向别引入引出车站时,桥梁设计将出现大量非标准线间距简支箱梁,其设计与批量预制问题亟待研究.以连镇铁路线间距5.3m简支箱梁为例,简要介绍梁部的设计情况,重点分析线间距增大引起的吊梁、架梁等一系列问题及解决措施,实现非标梁与线间距4.6m标准梁的统一设计与施工.研究结果表明:小幅调整既有的设计图纸和施工设备,能够满足非标准线间距简支箱梁的使用需求.

    • 摘要: Aiming at northwest widely distributed loess mudstone,this paper determines the geochemical composition,microstructure,mineral composition and physical and water properties of the mudstone and studies the dynamic change law of softening of mudstone in loess strata by means of X-ray diffraction, scanning of electron microscopy and physical properties test of rock based on Shangzhuang Tunnel project on Baoji-Lanzhou dedicated passenger line. The study results show that the high content of metal in the mudstone leads to darker color of the mudstone, the components are mainly quartz, calcite and plagioclase, accounting for 77% of the total minerals without montmorillonite and with only a small amount of illite and kaolinite. The mudstone under natural condition contains more clay particles,which are mainly in face-to-face or point-to-face contact. Under the action of water,the connection between the particles is gradually destroyed, resulting in damage of the rock internal structure and softening of the mudstone. Chemical composition and indoor test results show that the mudstone is almost of no expansion,but with a certain degree of disintegration.%针对西北地区广为分布的黄土地层泥岩,结合宝兰客专上庄隧道工程,通过X射线衍射、扫描电子显微镜以及岩石的物理水理性质试验等手段测定该泥岩地球化学成分、微观构造、矿物成分和物理水理性质,研究黄土地层泥岩软化过程中的变化规律.研究表明,该泥岩中金属元素的含量较多,导致泥岩的颜色较深,且其中矿物成分主要为石英、方解石及斜长石,占总矿物含量的77%,而蒙脱石含量为0,仅含有少许伊利石和高岭石;天然状态下泥岩含有较多的黏土颗粒,这些黏土颗粒间主要是面对面接触或点对面接触,在水的作用下,颗粒间的连接逐渐被破坏,导致岩石内部构造损坏,使得泥岩产生软化现象;化学成分及室内试验结果均表明,该泥岩几乎没有膨胀性,但是具有一定的崩解性.

    • 摘要: 目前我国高速铁路及客运专线铁路已进入高速发展时期,随着施工技术的成熟,不仅对内在质量要求越来越高,还对外观质量也提出了更高的要求.因此,处在桥梁最直观位置的防护墙的外观质量尤为重要.然而,因防护墙构造上具有下口大,上口小的特点,在施工浇筑过程中对振捣的要求很高,否则拆模后往往出现较为密集的大小气泡,往往在外观上不尽如人意,存在缺陷.在长大桥梁上,如何有效控制防护墙的施工质量和外观线形质量是施工中的难题.本文结合宝兰客运专线BLTJ-3标社棠渭河特大桥工程实例,对桥梁防护墙外观质量控制重点进行总结.

    • 摘要: 根据国家铁路局发布的《城际铁路设计规范》,城际铁路是指专门服务于相邻城市间或城市群,旅客列车设计速度200公里/小时及以下的快速、便捷、高密度客运专线铁路。《规范》颁布的时间是2015年,在此之前,我国已经有城际铁路开通。新旧标准的不同导致我国存在事实型城际铁路和规定型城际铁路两种类型,京津城际(时速350公里)等一批高铁型城铁,属于事实型城际铁路。城际铁路具有公交化的许多特点,对区域经济发展的推动作用比较明显,尤其是城际铁路运输低碳、节能功效明显,在完成相同运输工作量的条件下,消耗的能量比公路、航空少2到6倍。同时,城际铁路发展还将促进同城效应的出现,产生政治、经济、文化等发展的新的增长点,有利于推动区域和城乡协调发展,对就业和工业发展起到积极的带动和促进作用。目前,京津冀地区、长江三角洲、珠江三角洲、长江中游城市群等内部已经建起了多条城际铁路,城际铁路的优势也逐步得到发挥。不过,随着新型城镇化的推进,现有的城际铁路网络并不能完全适应经济社会的节奏,因此,近年来,国家和地方都把建设城际线作为铁路发展的重点之一。
