摘　　要：采用GeoStudio岩土软件SEEP/W模块对BBN水电站混凝土面板砂砾石坝进行渗流稳定计算分析,计算正常蓄水位、设计洪水位、校核洪水位3个高水位工况下的渗透比降,与坝基岩土的允许渗流比降进行比较,并通过与渗流安全监测实测资料分析成果进行对比分析,评价坝体及坝基的渗流安全性态,同时复核渗流计算的合理性。研究成果可对类似混凝土面板砂砾石坝设计和安全评价中的渗流稳定计算和复核分析提供一定的参考。The SEEP/W module of GeoStudio geotechnical software is used to calculate and analyze the seepage stability of the concrete panel sand gravel dam of BBN hydropower station.The seepage gradient under three high-water conditions,normal storage level,design flood level and check flood level,is calculated and compared with the allowable seepage gradient of the rock and soil of the dam foundation.The seepage safety state of the dam body and foundation is evaluated by comparing with the measured data of seepage safety monitoring.At the same time,check the calculation rationality of the seepage meter.The research results can provide some reference for the seepage stability calculation and review analysis in the design and safety evaluation of similar concrete face sand gravel DAMS.
