摘要
水库导流兼泄洪洞进口埋涵段开挖对原已稳定的古滑坡前缘进行"切脚开挖",挖除了部分古滑坡前缘的阻滑体,导致古滑坡的下滑力大于阻滑力,滑坡体发生滑动产生裂缝。结合现状,通过反演分析计算滑床泥岩的力学参数,对各种工况下的滑坡治理方案进行了计算,得出最不利工况为水位骤降工况。在此工况下,滑坡治理的工程措为施削坡、压脚工程量最小。
The reservoir diversion tunnel and the excavation of the original import of buried culvert has stable ancient landslide leading edge to cut the foot excavation,dig in addition to the part of the ancient landslide front resistance of sliding body,cause a downturn of the ancient landslide is greater than the slip resistance forces,landslide sliding cracks. Combined with the status quo,through the inversion analysis and calculation of mechanical parameters of slide bed mudstone under various working conditions of the landslide treatment scheme was calculated,it is concluded that the most unfavorable conditions for water level dropping conditions,on this condition,landslide engineering measures for cutting slope,and minimum quantities of foot.
