云南某水电站厂房边坡破坏机理模拟研究

滑坡的破坏模式和破坏机理是滑坡防治的重要依据,并对所采取的防治措施具有重要的指导意义.本文利用FLAC3D模拟了云南某水电站厂房边坡在施工开挖作用下的破坏模式和破坏的机理,通过模拟滑坡的位移变化特征以及分布规律,指出该水电站厂房边坡在施工开挖卸荷作用下并不是一个单纯的滑坡现象,也不是一个单纯的崩塌现象,而是一个以滑为主,局部产生崩塌的松散崩滑体.

Simulation study on destruction mechanism of Workshop Slop about somewhere hydropower station in YunNan province

The destruction model and destruction mechanism of the landslide are the important bases for the slop' s preventing and controlling, and it is also an effective direction on the preventing and controlling measure of landslide. This paper simulates the destruction model and destruction mechanism of workshop Slop which is excavated about somewhere hydropower etation in YunNan province using FLAC3D soft,, according to the displacement characteristic as well as the distribution rule of under Excavating, and propose that the displacement of workshop slop is neither only a landslide phenomenon nor a, single falling phenomenon, but, is a loose falling and sliding mass which primarily slides and go with the collapse simultaneously in the part of landslide.
