摘要
对龙滩水电站左岸蠕变岩石滑坡体变形及其主要影响因子变化情况进行了测量,测量项目包括地下水位、深部岩体水平变形、岩体分层变形和坡面表面测点水平位移.对测量结果进行分析表明,蠕变体B区岩体主要变形发生在570 m高程附近,并受地下水位影响明显;大坝蓄水时,对蠕变体稳定不利.
The rock mass deformation of high rehological rock slope were determined during the excavation period by the common ground surveying method in the left bank slope of Longtan hydraulic power generation station. The surveying items include the horizontal displacement of deep rock mass,the underground water level, the lean layers＇ deformation of deep rock mass and horizontal displacement of the slope surface. All the results show that the main deformation of the B distraction position locates at the 570.0 m altitude slope,the deformation of the slope is correlative to the underground water and the water storage is always harmful to the stability of the slope.
