摘　　要：填埋是处理城市固体废弃物（ＭＳＷ）的主要方法，对现代卫生填埋场进行设计和审查时均需进行广泛的土工分析，正确选择废弃物的工程性质对填埋场设计工作极其重要。由于ＭＳＷ构成极不均匀，其工程性质变化范围很大，并随时间而变，而且很难进行直接量测。本文根据收集到的资料，给出了ＭＳＷ某些工程性质如容重、含水量、孔隙率、渗透性、持水率、凋蔫湿度、抗剪强度和压缩性等的典型值，可供现代卫生填埋场进行初步工程评价时作参考。Landfilling is the most important controlled method for municipal solid waste disposal. The design and permitting of landfills requires performing comprehensive geotechnical analyses. Correct selection of engineering properties of waste materials for using in landfill design is of paramount importance. The engineering properties of waste materials vary within broad ranges, change significantly with time, and is not easily amenable to direct measurement, due to heterogeneity and hard inclusions. In this paper, typical values for engineering properties of municipal solid waste are presented , such as unit weight, moisture content, porosity, hydraulic conductivity, capacity, wilting point, shear strength, and compressibility. These properties are presented merely as a guide for preliminary engineering evaluation for designing soild waste landfills.
