圆形桩板墙在某高陡斜坡路基边坡加固处治设计中的应用
|
摘要
以某高速公路K102+100—K102+128段高陡斜坡路基边坡加固处治为依托,进行了详细的设计方案比选,最终确定采用圆形路肩桩板墙方案,同时对圆形路肩桩板墙开展了深入的设计、计算分析,提出桩板墙设计流程,并对施工后的圆形路肩桩板墙进行检测与监测,核实桩板墙理论计算桩顶水平位移与实际桩顶水平大小关系和原因,验证圆形路肩桩板墙加固处治效果及其使用范围,为类似工程的圆形桩板墙加固处治设计和施工提供一定的借鉴和参考价值。
Relying on the slope reinforcement treatment of steep slope subgrade of an expressway, this paper conducted detailed comparison and selection on the design schemes, and circular pile-plank wall was finally confirmed. At the same time, the design process of pile-plank wall was raised after in-depth design, calculation and analysis conducted on the circular pile-plank wall. Detection and monitoring on the circular pile-plank after construction were done as well so as to verify its reinforcement treatment effect and range of application, which could be used as reference in the design and construction of reinforcement treatment design of circular pile-plank wall of similar projects.
