摘要

摘要: 结合地下水位监测与降雨量监测结果,对龙滩水电站左岸蠕变体B区边坡位移监测资料进行综合分析,认为边坡蠕变岩体位移主要发生在高程520m以上,且强风化线或蠕变岩体折断面控制着边坡岩体的变形,由于边坡排水、坡体压脚,岩体变形速率逐渐变小,目前已经基本稳定。应加强边坡强风化线或蠕变岩体折断面附近的位移监测,特别是蓄水期监测;同时要保证地表和地下排水系统的正常运行。

Abstract: This paper analyzes the deformation monitoring data in the creeping rock slope B on the left bank of Longtan Hydropower station by considering the monitoring data of ground water levels and rainfall. The results show that deformation of creeping rock slope occurs above 520 meters in the elevation, and the strong weathering line or creeping rock mass breaking face controls the rock mass deformation of slope B. With drainage and loading at the toe of the slope, deformation velocity of rock mass is gradually reduced and almost reaches a steady state over time. The authors conclude that deformation monitoring near the strong weathering line or creeping rock mass breaking face should be continued, especially during the impoundment period, and therefore surface and ground water drainage systems could thus be well maintained.
