热源法在水库渗漏勘察中的应用

摘要

火山口附近玄武岩地区因其地质条件复杂，一直以来对该类地区的水库渗漏勘察较为困难。应用热源分析法对该类地区某水库渗漏区进行探测。首先将温度作为天然示踪剂，通过对所布置钻孔的温度观测，以温度场的变化为研究对象定性地确定了该水库的集中渗漏区，并通过水位观测、井下电视监测等方法进一步验证了该水库的集中渗漏区。之后，应用平面热源法定量地估算出了该集中渗漏区的渗漏量。%It has been difficult to investigate the leakage of reservoir located at the volcano and basalt region due to its complex geological conditions .This paper aims to apply the heat source analysis method to analyzing the leakage of reser-voir at this region .The water temperature is first taken as a natural tracer .Then the concentrated leakage area of reser-voir is qualitatively determined by observing the variation in the temperature of drilling arranged region .The leakage area of the reservoir can be further verified by using the observation of water level and underground TV .Additionally , the leakage quantity of the leakage area is estimated by applying the plane heat source method .
