摘　　要：百色水利枢纽在蓄水运行以来,银屯副坝左垭口和右垭口的渗流特性表现出较大差异。为分析此差异,依据坝体渗流渗压、绕坝渗流和坝后渗流量监测数据,从渗压水位变化过程、渗压水位与上游水位相关性、坝体浸润线等方面,分析并评价大坝渗流特性与渗流状态。结果表明,右垭口可能存在通过右岸山体与上游库水相通的渗漏通道。该方法可为同类工程监测资料分析提供借鉴。Since the Baise hydro project was in storage operation,the seepage characteristics of the left mountain pass and the right mountain pass of the Yintun auxiliary dam appeared large difference.Based on the monitoring data of dam seepage pressure,seepage flow around the dam and seepage flow behind the dam,the dam seepage characteristics and seepage state are discussed from the aspects of seepage pressure level change process,the correlation between the seepage pressure level and the upstream water level and the phreatic line.The results indicate that there may be a leakage channel in the right mountain pass that communicates with the upstream reservoir through the right bank mountain.The analysis ideas can provide reference for the analysis of monitoring data of similar projects.
