摘要
山谷型卫生填埋场是我国卫生填埋场建设的主要形式之一。本文借鉴无粘性坝体边坡的容许安全系数,反算求得不考虑内聚力的垃圾可能最小内摩擦角。利用这个内摩擦角计算坝体所受的主动压力,从而计算垃圾坝的抗滑、抗倾覆及坝基的稳定状态。初步建立了一套评价此类型填埋场堆埋体安全稳定性的方法,并通过对一工程实例的分析,证明了该方法是可行的。
Sanitary landfill is one of main methods to dispose municipal solid waste, and landfill in valley is an important form. The essay uses the factor of nostickiness dam slope to calculate the minimum innerfriction angle and initiative pressure on waste dam, by which the stability state of dam resistsliding and dam resistoverturn and damslope stability can be calculated. Two formulas for calculating initiative pressure and the arm of force are provided. A set of method that evaluates the stability of waste body on municipal solid waste landfill in valley is established. It is feasible testified by an example.
