土坝渗漏预示着存在安全隐患,必须准确确定渗漏点和渗漏情况,以便采取补救措施,但一般采用的确定渗漏源的方法既费钱又费时。介绍了美国里弗水库大坝查找渗漏源的新方法。 Leakage from an earth dam indicates a potential safety hazard. Leakage points and seepage conditions must be accurately identified for remedial action, but the commonly used method of determining the source of a leak is both costly and time-consuming. This paper introduces a new method to find the leakage source of American Rivers Reservoir Dam.
