锚杆抗滑桩加固边坡工程动力稳定性分析
|
摘要
锚杆抗滑桩加固边坡具有良好的抗震性能,目前这方面的研究资料还不多。结合大理西站边坡工程,应用拟静力法、时程分析法以及新近提出的有限元强度折减动力分析法对锚杆抗滑桩加固边坡进行动力稳定性分析。本文描述不同方法的计算特点和计算过程,比较不同的计算方法的异同点,分析锚杆抗滑桩的抗震性能与边坡的动力稳定性,以确保工程安全。研究成果可供类似工程设计参考。
The seismic performance of anchor anti-slide pile is strong,however,dynamic research data on this topic are scarce.The pseudo-static method,time-travel analysis method,and strength reduction dynamic analysis method were adopted to study the dynamic stability of this support form through an actual project conducted at a railway station in Dali.This study describes the entire application process and reveals the differences in these methods.In addition,the dynamic stability of this slope and the seismic performance were studied to ensure the safety of this slope.These research results can provide a reference for similar projects.
