基于SoilWorks软件的土质边坡分析

Analysis of soil slopes based on SoilWorks software

本文结合某高边坡,采用SoilWorks软件中的极限平衡法、强度折减法分别进行施工阶段模拟,并将锚索轴力计算结果与监测资料对比,分析结果表明:(1)采用极限平衡法计算结果偏安全;(2)锚杆(索)格构梁支护结构对该边坡起到了有效加固作用;(3)有限元计算模型及参数取值较合理;(4)在边坡设计及施工过程中应考虑锚索预应力损失的不利影响。

Based on the high slope,both limit equilibrium method and strength reduction method by the SoilWorks software are used to simulate construction stage respectively. Compared the anchor-cable axial force calculation with monitoring data,the analysis results are as follows：（ 1） The calculations by limit equilibrium method is more safer;（ 2） The structure with anchor（ anchor-cable） and grid beam has played an effective role in strengthening the slope;（ 3） The finite element method model and the parameter values are more reasonable;（ 4） In the process of design and construction,we should consider the adverse effect by the loss of anchor-cable prestress.
