Research on Current Situation of Mechanical Property Change in Landfill Soil in Freeze-thaw Cycle
Author(s): 
Pages: 86-90
Year: Issue:  2
Journal: Journal of Liaoning Institute of Technology(Natural Science Edition)

Keyword:  垃圾填埋场土体冻融循环FLAC3D数值模拟;
Abstract: 针对垃圾填埋场中土体冻融循环后力学性质的改变以及所产生的土体不均匀沉降问题,通过对大量国内外文献的阅读,分析了垃圾填埋场土体冻融循环后力学性质改变的机理,同时就目前国内外对土体冻融循环研究存在的问题,利用试验和数值模拟相结合的研究方法,为实际工程提供科学的理论依据.如在垃圾填埋场封场时,利用大型机械对表层土体压实来减少垃圾填埋场的不均匀沉降.
