让压层厚度对让压抗滑桩预控工程效果的影响研究

Study on Influence of Yielding Layer Thickness on Pre-Control Engineering Effect of Yielding Anti-Slide Pile

创新性工程设计是解决层状岩岸坡支护加固工程问题的主要思路,具有十分重要的工程意义。以具体工程为背景,通过现场实验的方式,探讨让压层厚度对抗滑桩支护效果的影响。试验结果显示,当让压层厚度为10cm时,桩身和坡体的位移量增幅不大,但桩身的侧压力值明显减小,为最佳设计厚度,建议在工程设计中采用。

Innovative engineering design is the main idea to solve the engineering problems of layered rock bank slope support and reinforcement,which has very important engineering significance and value.Based on a specific project,this study discusses the influence of the thickness of yielding layer on the supporting effect of anti-slide pile through field experiments.The test results show that when the thickness of the yielding layer is 10cm,the displacement of the pile body and the slope body will not increase much,but the lateral pressure of the pile body will obviously decrease.The optimum design thickness is recommended for engineering design.
