【摘要】 FLAC3D是岩土工程中广泛应用的软件。本文主要介绍强度折减理论的基本原理,利用基于强度折减法的FLAC3D软件,对某高速公路K377+230～K377+520段滑坡体进行数值模拟。计算边坡在自重作用达到初始化平衡状态时,边坡的横向与竖直方向的应力与位移,分析出边坡的破坏机制为牵引式滑坡,通过强度折减理论计算出边坡的稳定系数为0.97,由剪切应变增量云图确定边坡的滑动面。更多还原

【Abstract】 FLAC 3D is a widely applied software in geotechnical engineering.We mainly introduce the principle of strength reduction theory.Numerical simulation on the K377+230~k377+520 section of a highway has been made by FLAC 3D sofeware based on strength reduction theory.To calculate the slope lateral and vertical stress and displacement when the slope gets to the initialization equilibrium condition in dead weight function,then to analyze the result that the slope failure mechanism was retrogressive landslide;after that to calculate the slope stability coefficient as 0.97 through the strength reduction theory,finally to determine the sliding surface by the shear strain increment chart.更多还原
