【摘要】 为查明某垃圾填埋场库坝工程质量，在坝脚进行现场直剪试验时试验段出现渗水与软化现象，因此为配合稳定性评估工作必须对坝体开展水文特征研究工作。文章按水的赋存部位、来源特点和贯通性，分为两类三种滞水情形：堤坝滞水（临空坡面保护层、堤坝堆填主体）、坝基基岩裂隙承压水，并建立了水力联系，最终发现坝体内粉土筑填体是安全隐患部位，受坝内滞留水及堤坝迎水面渗沥入渗浸润易出现软化。更多还原

【Abstract】 In order to find out the quality of the reservoir dam project of a waste landfill site,water seepage and softening occurred in the test section during the on-site direct shear test at the dam toe. Therefore,in order to cooperate with the stability assessment,it is necessary to carry out hydrological characteristics research on the dam body. According to the location, source characteristics and connectivity of water,it is divided into two types and three types of water retention situations:dam water retention(free slope protection layer,dam filling main body),dam foundation bedrock fissure confined water,and established hydraulic connection. Finally,it is found that the silty soil filling body in the dam body is a potential safety hazard location, and it is easy to soften due to the retained water in the dam and the seepage infiltration infiltration infiltration of the upstream face of the dam.更多还原
