摘　　要：近年来中国各大城市为解决城市交通问题而大力兴建地铁工程,由此引发的工程环境问题也越发明显。本文对国内外地铁荷载作用下土体的动力响应理论、地铁荷载下粉性土动力特性试验以及地铁隧道长期沉陷等研究进行评述,分析和总结了地铁循环荷载作用下粉性土研究中存在的问题,并提出了今后研究的发展趋势。In recent years,many subway-tunnel engineerings have being built in big cities of China for solving traffic crowd problem,but also met some engineering environment problems in building.In this paper,the researches on dynamic response theory of soil and test of dynamic properties of silty soil under subway loading,as well as long-term settlement of subway-tunnel in home and abroad are introduced in detail.The current problems in research of silty soil under cyclic loading from subway are analyzed and summarized.The development trend of the research in future are pointed out also.
