断层边坡地震动载效应的数值模拟

open access: yesDizhen xuebao, 2023
地震荷载作用下,断层两侧边坡稳定性一直是研究重点,本文主要探讨动态加载对不同位置坡体产生的地震动效应。首先,建立一个截面大小为500 km×100 km的有限元二维动态铲形断层模型,在地表断层两侧构建对称边坡来模拟滑坡地形。然后加载脉冲震源,通过对震源(深度为14 km)处节点指定加速度的方法,模拟计算地震发生后100 s内地震波传播对距断层分别为1 km,30 km及100 km的不同边坡震动产生的影响。结果显示:边坡震动强度随着震源距的增加而快速衰减,下盘的衰减比上盘更为强烈;距断层相同位置处 ...

植物根系吸水对非饱和土边坡稳定性影响的分析

open access: yesShuitu Baochi Xuebao, 2022
为了量化植物根系吸水对非饱和土边坡稳定性的影响及为植被护坡的植物种类选择提供参考,采用COMSOL Multiphysics建立二维边坡,模拟不同根系形态、根长及降雨条件下的根系吸水引起的非饱和土边坡孔隙水压力的分布变化,并采用极限平衡理论对边坡稳定系数进行定量计算。结果表明:指数形根系吸水产生的吸力最大,比裸坡增大4.2倍,抛物线形根系吸水产生的吸力最小,但仍比裸坡增大2.7倍;根系越长吸水影响深度越大;根系越短,产生的吸力越大,且吸力在边坡表面的变化越显著;短期降雨后,含根系边坡吸力比裸坡高12 ...
