摘　　要：垃圾的构成受多种因素的影响,十分复杂,且随时间改变,因此垃圾的工程性质变化幅度大,而且不易量测,给设计参数的确定带来了困难。根据中国和美国的资料,分析和比较垃圾土的组成以及重度、含水量和相对密度这3个最基本的物理性质指标。比较结果显示,中国的垃圾土重度测试值与美国的接近,而含水量和相对密度测试值都较美国的高。最后,对垃圾土物理性质的现场和室内试验方法进行分析和探讨,得到了一些有益的结论和建议。In present,landfill is still the most important controlled method for municipal solid waste disposal in China. Correct selection of engineering properties of waste materials is of paramount importance. The properties of waste materials vary within broad ranges,change significantly with time,and are not easily amenable to direct measurement due to heterogeneity and hard inclusions. The components,unit weight,water content,and specific gravity for Chinese and USA waste materials are discussed in detail. The unit weight of Chinese waste is similar with USA waste,but the water content and specific gravity of Chinese waste are greater than those of USA waste. The testing methods for these properties are also presented. Some valuable results are concluded and discussed.
