利用冲击试验测量平面中某一点渗透系数的特点,第一次将冲击试验应用到堤坝渗漏通道的探测的工程应用之中.以岭澳水库工程为例,通过一系列冲击试验的测量,判断得到桩号0+275~295区间的坝段存在渗漏通道.运用温度示踪以及电导率探测的方法,分析得到渗漏通道的位置范围,与冲击试验测量结果基本一致.对0+275~295坝段区域进行灌浆处理以后,通过记录水库库水位及坝后量水堰流量变化,发现灌浆效果明显,证明冲击试验的测量结果的正确性.冲击试验在寻找渗漏通道以及对土石坝进行检修加固等方面有明显的实际工程意义和广阔的应用前景.
利用遲擊試驗測量平麵中某一點滲透繫數的特點,第一次將遲擊試驗應用到隄壩滲漏通道的探測的工程應用之中.以嶺澳水庫工程為例,通過一繫列遲擊試驗的測量,判斷得到樁號0+275~295區間的壩段存在滲漏通道.運用溫度示蹤以及電導率探測的方法,分析得到滲漏通道的位置範圍,與遲擊試驗測量結果基本一緻.對0+275~295壩段區域進行灌漿處理以後,通過記錄水庫庫水位及壩後量水堰流量變化,髮現灌漿效果明顯,證明遲擊試驗的測量結果的正確性.遲擊試驗在尋找滲漏通道以及對土石壩進行檢脩加固等方麵有明顯的實際工程意義和廣闊的應用前景.

It is the first time to detect the leakage channel of the dam by slug test;for that the slug test is used to get the permeability coefficient of a point. Based on the Ling′ao Reservoir project,the leakage channel of the dam is detected at the zone pile No. 0+250–295 after a series of slug tests. Using the method of temperature tracer method and detecting of eeeeeeeeeee,it is found that the result is basically the same with the result gotten by slug test. After grouting to the zone of pile No. 0+275–295,there is an obvious effect through the reservoir water level and the flow rate of dam weir. So it demonstrates the correctness of the measuring result of slug test. There is great practical significance and broad application prospects for the application of slug test to detect the leakage passages and overhaul reinforcement of earth-rock dam and riverbank.
