某高速公路路堑边坡FLAC数值模拟分析

Numerical Simulation Analysis for the Slope of a Highway by FLAC

本文主要阐述了对某高速公路进行数值模拟分析并加固的具体过程。首先对沿线路堑和路堤进行了边坡设计,采用合理的加固方案对边坡进行加固。通过对边坡采用锚固的治理措施,既能保持高速公路沿线整体性,又能达到加固的目的。接着应用数值模拟的方法,分析边坡加固前后的稳定性。最后简单设计了路堑边坡坡面防护。

The numerical simulation and reinforcement analysis for the slope of a highway by FLAC (Fast Lagrangian Analysis of Continua) are mainly illustrated. Firstly, the slope gradient for both cutting and embankment side slopes is desinged, proper method is used for enforcement of the slop. The reinforcement method is effective to keep the integrity and take bolt anchorages of highway slopes. Secondly, The FLAC is used for analysing the slope stability before and after enforcement. Thirdly, the slope protection for cutting side slope is simply designed.
