摘要
垃圾填埋场是一类特殊工程 ,其安全稳定性一直是研究的热点和难点。本文借鉴成熟的工程力学思想 ,将分析山谷型垃圾填埋体的安全稳定性转化为分析垃圾坝稳定性。利用已知的稳定填埋场边坡有关性状 ,反算出垃圾土可能最小综合内摩擦角 ,利用这个参数来计算填埋体在三种典型状态下对垃圾坝产生的最大作用力 ,从而来判断垃圾坝的稳定性。探索了一套分析山谷型填埋场填埋体稳定性的方法并提出了两个公式 ,对于该类型垃圾填埋场建设具有指导作用。
Waste landfill in valley is a special engineering,which usually has a waste dam in the extrance of valley.Its safety and stability is a focus of research and it can be evaluated by the waste dam's according to the accepted theory of the engineering mechanics.The possible comprehensive smallest inner-friction angle is obtained by analyzing the stable slope of the landfill and is used to calculate the potential force produced by waste body on waste dam in three typical states,which can be used to estimate dams stability.Two formulas and a series of methods that is valuable for construction of this kind of landfill is proposed to evaluate the safety and stability of municipal solid waste landfill in valley.
