某固体废物处置场水文地质试验应用实践

Application Practice of Hydrogeological Test in a Solid Waste Disposal Site

摘要: 场地的安全稳定对处置场的正常运行至关重要，地下水是影响场地安全稳定的一个重要因素，通过水文地质试验可以获取场地岩土体的渗透特性，为场地的稳定性计算提供水文地质参数。本文通过试坑渗水试验、钻孔压水试验、注水试验、抽水试验等水文地质试验得到了处置场岩土体的渗透特性，并获取了相应的水文地质参数，为进一步的分析计算提供了技术支撑，对处置场的安全稳定具有十分重要的作用。

Abstract: Site safety and stability are very important to the normal operation of the disposal site, while groundwater is a key point affecting the safety and stability. Hydrogeological tests can be applied to get hydrogeological parameters for site stability calculation and to define the permeability characteristics of the rock and soil. In this paper, kinds of hydrogeological tests such as pit seepage test, borehole water pressure test, water injection test and pumping test, were carried out to explore the rock and soil permeability characteristics of the disposal site and get the corresponding hydrogeological parameters for further analysis and calculation, which played a decisive role for site safety and stability.
