重庆市某垃圾填埋场填埋体的强度特性试验

随着经济和社会的发展，越来越多的垃圾场严重威胁着城市的发展．通过在现场采集垃圾土样，在室内利用直接剪切仪及三轴剪力仪等仪器进行了土工试验，根据试验结果分析研究了城市生活垃圾填埋体的结构自稳性与垃圾土强度的关系、垃圾土强度参数的变化规律及影响因素．对新建垃圾场的设计与施工及封场后的垃圾场的再利用有着实际的参考意义．结果表明：垃圾土的组成成分、颗粒大小、含水量，压实方法、压实程度和填埋时问、降解程度等因素都直接影响着垃圾土的强度特性．

Experimental Research on Municipal Solid Waste Landfill's Strength Character in a Refuse Dump of Chongqing

With the development of economic and society,more and more waste landfill gradually threaten to the development of the city.Some special tests are done to study the relationship of the Municipal solid waste(MSW) strength and the stability of MSW landfill structure.A geo-technical test with the soil samples collected at the scene is done in the laboratory through direct sheared device and the thri-axial sheared device,the disciplinarian and factors are analyzed.The results are referenced to the design and construction of new-built MSW and finished rubbish field.It is shown that some parameters such as composition,particle magnitude,water content,compressing method,intensity and time,will greatly affect the strength character of MSW.
