基于PFC2D的岸坡覆盖层失稳堵江模拟研究
Simulation Research on River Blocking by Instable Cover Layer of Reservoir Bank Based on PFC2D
摘要
Abstract
Based on the PFC2D particle flow method,the cover layer model of reservoir bank is established,and the failure processes of cover layer under different water levels of reservoir are simulated and the heights of dammed weir in river are predicted.It is concluded that the higher the water level of reservoir,the higher the dammed weir height.When the proportion of saturated soil in cover layer is 1/3,the damage scale is larger and the height of damming weir is higher than that under other water levels,which means that there is more dangerous water level range.When the water level is lower than the dangerous water level,the main failure mode is slope collapse.In the dangerous range of water level,the slope results in overall failure.When the water level is higher than the dangerous range,the destruction is mainly the saturated soil.This method is not suitable for the simulation of dynamic process of reservoir water level fluctuation,and is only applicable to the simulation under static water level.关键词
