摘    要:人工处理台州市黄岩区生活垃圾土试样,分析组分后作固结和直接剪切实验。结果表明:在试样的孔隙比一定时,其瞬时沉降量随含水率的提高而增加,前期增加速度更快;e-lg p曲线兼有黏性土和密实砂土曲线特征;剪应力随剪切位移呈现逐渐硬化的曲线;抗剪强度与法向应力基本成直线关系,符合库仑定律;当含水率在40%~50%时,随含水率增加,黏聚力明显增大,内摩擦角减小。

关 键 词:城市生活垃圾  成分分析  抗剪强度参数  压缩特性

Abstract:For the artificially treated municipal solid waste in Huangyan district of Taizhou city,the consolidation test and direct shear test are carried out after composition analysis.Experimental results show that at a definite void ratio,the instantaneous settlement of the treated waste increases with the increasing of water content and increases faster at the early stage,and its e-lgp curve has the characteristics of both clay and compacted sand.The shear stress-displacement curve shows a gradual hardening trend.The shear strength and vertical stress have a linear relationship and meet with Coulomb’s law.When the water content is 40% ~ 50%,the cohesion increases while the internal friction angle decreases with the increasing of water content.
Keywords:municipal solid waste  composition analysis  shear strength parameter  compression property
