摘要： 通过对湖区水文地质条件、岩溶发育条件、及渗透性分析，确定了湖区地层的相对透水条件，进而分析了湖区渗漏的方式、及渗漏量。总结得出: 湖区东西两侧相对隔水，主要由北向南渗漏；湖区渗漏形式为裂隙―溶隙型渗漏；渗漏较弱，渗漏量为7.21 m\+3/d；可不考虑人工湖渗漏，不作防渗处理。

Abstract: This paper documents a case study of the analysis on the seepage aspects of a manmade lake. The hydrological and geological conditions, karst terrain development as well as the seepage properties at the lake area are studied so that the seepage conditions and boundaries could be determined as a result of these analyses.  The directions and the quantities of the seepage underneath the manmade lake are determined. The results show that the aquitard layers exist at both east and west side of the lake and the seepage mainly occurs from the north to the south throughout the bedrock fissures. The estimated total seepage quantity is 7.21 cubic meters per day and this quantity is a weak seepage compared with the size of the lake. It is concluded that the leakage prevention measure is not necessary for this manmade lake.
