小浪底水利枢纽工程左岸山体渗漏处理监测分析

Monitoring Analysis for Anti-Seepage Treatment on the Left Bank Mountain of Xiaolangdi Multipurpose Dam Project

小浪底水利枢纽工程,左岸山体的渗漏问题突出,为改善地下厂房的运行环境,确保左岸山体的稳定,结合左岸山体各部位渗漏观测情况、水文地质条件以及同位素综合示踪法与物探方法对集中渗漏通道的探测结果,于2004年下半年采取一系列防渗补强工程措施。通过对防渗补强前后渗水量的分析,表明此次防渗补强效果显著。

Seepage problem has been giving major concern for the left bank mountain of Xiaolangdi Multipurpose Dam Project. In order to improve the environment on operating the underground powerhouse, and hence ensure stability of the left bank mountain, a series of strengthening measures have been taken in the second half year of 2004, with consideration of seepage monitoring, hydro-geological conditions of every location of the left bank mountain, as well as of detection results of the main seepage paths with isotope tracing method and geophysical method. Upon comparison of seepages measured before and after the anti-seepage treatment, conclusion is made that strengthening effect is prominent.
