库坝探漏新技术及工程处理的新方法

New Technique for Detecting Seepage underneath Earth Embankment and New Method of Treatment

库坝渗漏影响工程运用和效益的充分发挥,准确探测渗漏部位是治漏工程处理的前提。作者采用放射性同位素单管探漏法,简便准确地测定了五个水库库区的严重渗漏点,并采取上截下堵灌注法进行灌浆处理,取得了良好效果。

Seepage undemeath earth dams influences the operation and development of its economic benefits.Accurate detection of the location of leakage is a prerequisite for engi-neering treatment.The sites of serious seepage from s reserviors were determined exactly by the simple method of using radioactive isotope installed in a single pipe.Good results were achieved by grouting of cutting off on the upstream side and blocking up on the downstream.
