嵌岩桩水平承载力试验研究

摘要

随着港口、公路、铁路事业以及高层建筑的飞速发展,水平受荷嵌岩桩在港口、桥梁、码头等工程中得到了广泛应用,研究嵌岩桩的水平承载性能具有重要的工程意义.现场试验是研究嵌岩桩承载机理最可靠的手段,但是由于受到历史条件和工程条件的限制,高质量、完整的嵌岩桩现场原位水平承载力试验还比较缺乏.以浑河大桥工程为依托,对其中的两根试验桩基进行现场原位水平加载试验,研究了在水平荷载作用下桩顶的荷载-位移曲线、桩身弯矩分布情况,最后对提高嵌岩桩在水平力作用下的承载力提出了一些建议.%With the rapid development of port, highway, railway and high-rise buildings, the horizontal load bearing rock socketed piles have been widely used in ports, bridges, docks and other projects.So it has an important engineering significance to study the horizontal bearing capacity of rock socketed piles.Field test is the most reliable method to study the bearing mechanism of rock embedded pile.However, due to the limitation of historical conditions and engineering conditions, high quality and complete in-situ horizontal bearing capacity test of embedded rock pile is still relatively scarce.This paper studied the load-displacement curve and bending moment distribution of piles under horizontal load based on the field test of the two rock socketed piles in Hun River Bridge.
