摘要
结合响洪甸大坝渗流实测资料,通过定性和定量分析综合评价了坝基的渗流性态;并对坝基渗流观测孔孔水位普遍偏高、且与上游库水位变化基本同步的异常性进行了物理成因解析。分析成果表明,部分坝块坝基帷幕防渗效果不够理想,坝基排水不够通畅。建议加强监测的同时采取相关工程措施,改善大坝的渗流性态。
Based on the observational data, the seepage behavior of the Xianghongdian Dam foundation is evaluated synthetically
by qualitative and quantitative analysis. The causes of the higher-than-normal water levels of foundation seepage observation
holes, and the synchronous water level variation with the upstream reservoir level are analyzed. The results show that the
seepage prevention effect of some foundation curtains is not so good, and the foundation drain is not so effective. It is suggested
that monitoring be strengthened and measures be taken to improve the seepage behavior.
