| 摘 要： | 立足于茅草坡岩体的工程地质背景,通过详细调查发现:茅草坡内存在倾倒变形、层间剪切、滑移和坡面拉裂等变形现象,这些现象都具有一定的特征和特定的意义.对茅草坡内的变形现象和监测数据进行分析表明茅草坡不稳定斜坡变形破坏机理存在转化,由最初的倾倒一拉裂变形模式转化为滑移一拉裂失稳模式.三峡库区蓄水和周期性调水使茅草坡坡脚成为消落带区域,对茅草坡稳定性不利,加速了其发展变化.

| Abstract: | The paper is based on the rock mass geo-engineering background of the Maocaopo slope.Detail survey reveals some phenomena,including topple,shear,slip and tension,which have certain characteristics showing special meaning.After analyzing the deformation phenomena and monitoring data,the conclusion that the unstable slope deforming mode shows change charactistics,which change from toppling-tension mode to slipping-tension mode.The impounding and periodic adjustment in the Three Gorges Reservoir results in water fluctuation zone in the foot of the Maocaopo slope.This is not good to the stability of the Maocaopo slope and accelerates the development of the slope. |
