摘要
为了防止雨水流入垃圾中形成的渗滤液等多种有害物质流入地下污染地下水以及周围环境,现代垃圾填埋场都设置了防渗系统。防渗系统一般由无纺布、防渗材料以及膨润土土工毯等组成,由于在热应力、拉应力以及穿刺等各种因素的作用下,可能导致防渗系统破坏而使有害物质流入地下。介绍了造成防渗系统破坏的原因及其防治措施。
The waste landfill should be designed no leachate that may include hazardous materials flowing into surrounding ground and water over long period of years. A seepage system composed of geomembrane,geotextile and GCL is installed on the bottom and the side slope of a waste landfill. The seepage system is considered to bear various forces,such as tensile force,thermal stress and puncture, and it would be damaged under the influence of various factors. The main reasons of damage of geomebrane are analyzed,and the measures and suggestions on prevention are presented.
