摘　　要：襄樊市洪山头垃圾填埋场投资和建设周期均受控于压实粘土坝和渗滤液与沼气收集系统两个关键因素,技术难度大。基于有限元分析结果确定土坝边坡的最佳坡度,采用土工格栅加筋土和包裹式坡面结构新技术加固坝体边坡。介绍一种收集管设置在砾石盲沟内的渗滤液与沼气收集系统,该系统的渗滤液收集和防淤塞能力强,可有效防止收集管弯曲和断裂。The compacted clay dam and percolate and methane collection system are two key factors that control the investment and construction period of the solid waste landfills of Hongshantou in Xiangfan city. Based on the results of Finite Eelement Method (FEM) for the stability of dam slope, the optimum angle of slope is determined. The techniques of the reinforcement dam slide slope with geogrid and packaged slope surface structure are presented. The percolate and methane collection system, which the collection pipes are installed in the blind ditches that are consisted of gravels is introduced. This system can avoid silting, collect percolate easily, and protect the pipes from bending and damaging.
