摘　　要：采用有代表性配比的人工配料垃圾土试样对瞬时模量变化规律进行了试验研究,结果表明:垃圾土有机质含量、初始含水率、初始孔隙比及降解程度的变化对瞬时模量都有影响,并得到了各影响因素下的变化规律。结合垃圾土自身特性对各因素影响机制及结果进行了分析,这些结论对未来的填埋场变形研究及工程设计是非常有意义的。Based on experiment using the typical artificial MSW to study the transient modulus changing of MSW is carded out. The study has shown that the transient modulus of MSW is changed when the organic content, the initial moisture, the initial void ratio or the degradation degree of MSW changing; and some changing laws due to influences of above-mentioned factors are obtained. The mechanism is analyzed combined with the property of MSW. These conclusions are very useful to the research of distortion of landfill and the design of landfill in the future.
