预应力锚索抗滑桩支挡结构在路基边坡防护中的应用研究

摘要

通过分析目前常用的治理公路路基高陡边坡的工程措施,得出预应力锚索抗滑桩支挡结构具有柔性支护、主动支护、经济合理等优点.分析了预应力锚索抗滑桩支挡结构计算理论,在计算理论中引用双参数法至土抗力模数和地基系数中,并将抗滑桩分为刚性桩和弹性桩两种物理模式进行计算分析.结合某一级公路边坡的边坡治理情况,对其计算和应用进行了介绍,通过静力水准仪对其中3个抗滑桩的沉降进行长达120 d的监测,结果表明,抗滑桩的沉降位移小,符合设计要求,证明了预应力锚索抗滑桩支挡结构具有良好的工程性能.%In this paper,by analyzing the engineering measures which are commonly used in the control of high and steep slope of highway embankment,it is concluded that the prestressed anchor Stabilizing Piles retaining structure has the characteristics of flexible support,active support and economic rationality.In this paper,the basic principle of the calculation of anchor pile structure is analyzed.In the calculation principle,the two-parameter method is used to calculate the soil resistance modulus and the foundation coefficient,and the Stabilizing Piles is divided into two kinds of rigid and pile-type physical modes.Combined with the slope control of a secondary slope,the application is itroduced,and the vertical settlement of the three Stabilizing Piless is monitored by the static level.The results show that the anti.The vertical settlement of the pile is small and meets the design requirements,and it proves that it has good performance.
