摘　　要：为深入探讨垃圾填埋场防渗系统破坏造成的环境污染问题,基于环境岩土工程和多孔介质渗流力学理论,对比分析了各种防渗结构模式的特点,研究了土工防渗系统的防渗机理,提出了今后填埋场防渗系统中涉及的关键环境岩土工程问题—水力与载荷耦合作用下填埋场防渗系统可靠性研究。结果表明,垃圾填埋场中渗滤液和填埋气体的释放传输环境工程效应直接影响到防渗系统的安全性和稳定性;采取双层复合衬垫防渗体系,能够有效提高填埋场抵抗环境污染的能力,为填埋场防渗体系的优化设计和防渗膜选择提供了技术支持。For further discussing the environmental pollution caused by the failure of anti-seepage system in landfill, based on the theory of mechanics of porous seepage and environmental geoteclmical engineering, the various structural styles were comparatively analyzed, the anti-seepage mechanism was studied, and the key problem, which is the reliability research on the anti-seepage system through coupling action of hydraulic power and loads, is put forward. The results show that the security and the stability of anti-seepage system are influenced directly by the environmental engineering effect of leachate and gas released in landfill; the resistant ability of environment pollution is improved by using double compound layer. It offers technical support for the optimal design of the anti-seepage system and the selection of geomembrane in landfill.
