将生活垃圾分为易降解材料、难降解材料和不可压缩的固体材料3大类，其比例为50％、15％、35％。在环境土工实验室，人工配制该比例的垃圾，采用超大型直接剪切试验仪器，进行了生活垃圾强度特性及抗剪强度参数的研究。研究表明，生活垃圾的强度与压缩时间和剪应变有关，且符合库仑定律，得到了初始孔隙比为2.9的生活垃圾在不同压缩时间及不同剪应变下的抗剪强度参数，黏聚力为9.69～15.64kPa，内摩擦角为18.73°～35.53°。

The materials of municipal solid waste(MSW)can be divided into three parts.They are respectively the materials of easily degradation,difficulty degradation,and incompressibility.Their proportions are 50%,15%,and 35%,respectively.Their shear strength properties and parameters are examined with an ultra-large direct shear test equipment.The artificial MSW is tested in a geo-environmental laboratory.The test results show that the compression time and shear strain are two key factors for MSW shear strength.The relationship between the shear strength and the vertical pressure applied on the test samples conforms to follow the frictional law of Mohr-Coulomb. Besides,the shear strength parameters of MSW are obtained with the initial void ratio equaling 2.9 under different compression times and different shear strains.The cohesion varies from 9.69 to 15.64kPa.The internal friction angle varies from 18.73°to 35.53°.
