摘　　要：渗漏是水库坝址区存在的主要工程地质问题。因渗漏具有隐蔽性,采用钻探或普通物探方法准确查明渗漏区非常困难。在霍林河水库大坝渗漏分析工作中,采用声呐流速探测仪进行大坝渗漏探测,获取各钻孔不同深度的渗漏流速。据此计算各渗漏区的渗透性,确定大坝渗漏区为强透水区和中-强透水区。渗漏区的确定为采取针对性的防渗堵漏措施提供了科学依据,相关分析方法可为类似工程提供借鉴。Leakage is a major engineering geological problem in the dam site area of reservoirs.Due to its hidden nature,it is very difficult to accurately identify the leakage area using drilling or common geophysical prospecting methods.In the leakage analysis of the Huolin River Reservoir dam,an acoustic Doppler current profiler was used to detect the leakage of the dam and obtain the leakage flow rate at different depths of each borehole.On this basis,the penneability of each leakage area was calculated,and the dam leakage area was determined to be a highly permeable zone and a moderately to highly permeable zone.The research provides a scientific basis for the formulation of antileakage measures,and the analysis method could serve as a reference for similar projects.
