The paper reviews the concept origin of loess collapsibility and the research status of collapsibility mechanism based on its microstructure,and discusses on the collapsibility mechanism from the perspective of unsaturated soil mechanics,then puts forward the concept of generalized collapsibility.

Study on Collapse Causes of Loess based on Experimental Methods;

Through investigating and analyzing several foundation engineering cases,researching deeply the forming mechanism of collapse in replace soil foundation,suggesting some kinds of methods to consolide the collapse?raplace soil foundation,and getting better results in many engineering practices.

This paper analyses and reseraches on the relations between microstructure of loess and its collapse property.
