丝绸厂滑坡相对于老房子滑坡稳定性略好，但在库水位骤降的情况下也有可能整体失稳。 - During the process of modeling , three conditions of reservoir water level ' s ascending , slowly descending and sharply descending are considered
模拟过程中分别考虑了库水位上升、库水位缓慢下降和库水位骤降三种工况条件。 - The collapsing scope of bank accumulation body of zipingpu reservoir in national highway 213 which caused by the sharply falling of water level of zipingpu reservoir is estimated according to the fem plastic zone graph
根据有限元法得出的塑性区图，对紫坪铺水库蓄水后水位骤降可能引起213国道紫坪铺库区库岸堆积体的坡角坍塌范围进行了估计。 - Then the stability of typical slopes in different conditions such as servoir water level ' s ascending , slowly descending and sharply descending are evaluated and forecasted by means of the limiting balance method and the numerical simulating method ( flac )
利用极限平衡法和数值法( flac )对库区内的典型斜坡在库水位上升、库水位缓慢下降和库水位骤降等不同工况条件下的稳定前景做出了合理的评价与预测。 - ( 6 ) conclusion was obtained by the analyzing the mechanics environment and the stability of the lanslide on the right bank after the dam built : the value of the rock mass stress increased and the tensile stress region obviously reduced , the direction of the principal stress was unchangeable the dam and the landslide were stable under the dangerous condition ( the reservoir and at the same time the earthquake was viii ) , but when the water lever suddenly fell and did not think of other force , safe factor evidently reduced , the dam and the landslide will be destroyed under the most dangerous condition ( the water lever suddenly fell and at the same time the earthquake was vi ) ; the stability of the landslide will be destroyed by the horizontal thrust under the most dangerous condition or ; the physical and mechanical parameter will be reduced due to long period filter , the landslide will be destroyed too
( 6 )建坝工程荷载条件下河谷岩体力学环境分析及右岸古滑坡体的稳定问题分析得出：建坝后河谷的岩体应力量值明显增高，同时左岸的张应力区的范围及量值明显减小，主应力的方向依然与模型的底边界垂直；大坝建成后逐渐蓄水阶段以及同时考虑本区最强地震力的作用等各种不同的工况条件时，滑坡体及坝体总体上仍处于稳定状态；水位骤降时，在未考虑其他外力作用的情况时，滑体的安全系数将显著降低。若考虑水位骤降及本区最大地震力的共同作用，坝体将在滑坡体下滑推力的作用下产生破坏；建坝后水平推力对右岸古滑坡体稳定性的影响分析可以看出，在最危险的工况条件下，坝体及滑坡体也将处于临界状态；在长期渗透变形的作用下，由于滑带的物理力学参数的降低而有可能导致坝体失稳破坏。
