【摘要】 基于FLAC3D数值模拟,对益阳鱼形山水库周边浸水路基边坡在天然状态、普通植被混凝土状态以及六角砖支护下边坡变形情况进行了对比分析,发现该路基边坡虽在常水位下处于稳定状态,但在内涝时期边坡安全系数过小,有发生滑坡坍塌的危险;在采用六角砖防护时,安全系数有一定幅度的增加,坡体内浸润线均有效降低,并小于内涝水位。更多还原

【Abstract】 Herein the deformation of slope along the soaking subgrade surrounding Yuxingshan Reservoir, Yiyang, in natural, general vegetation-concrete, and hexagonal brick supporting conditions were compared and analyzed depending on FLAC3D numerical simulation. It was found that the slope has too small safety factor in the period of waterlogging with the risk of landslide collapse, though it is stable under normal water level; if protected by hexagonal brick, the safety factor increases to certain extent and the phreatic line in the slope is decreased and lower than the level of waterlogging.更多还原
