洪屏抽水蓄能电站上水库地下水动态分析

摘要

洪屏抽水蓄能电站由于引水隧洞和地下厂房施工，改变了天然地下水流场。为研究施工对于地下水的影响，需要对区内地下水水位动态进行观测和分析。上水库库周多数山体地下水位和相对隔水层均高于正常蓄水位，不存在渗漏问题。由上水库各区域钻孔水位动态曲线图分析可得，上水库的防渗及监测重点在西北垭口、西副坝与西南副坝之间山体及南库岸地段山体。%As the reason of construction ,original flow field of groundwater in Hongping Pump-storage Power Station has changed.For studying the influence of construction to groundwater and guiding the further construction ,observation and analysis of groundwater level dynamic is needed .The most groundwater levels and relative impermeable layers in sur-roundings of upper reservoir are higher than normal pool level ,there are no leakage problems .According to the curve of groundwater level dynamic in each region of upper reservoir , the key areas of seepage control and monitoring are the mountain between northwest pass area ,west auxiliary dam and southwest auxiliary dam ,and the mountain in south reser-voir bank .
