RESEARCH PROGRESS IN LOESS LIQUEFACTION AND SEVE-(RAL) PROPOSALS

This paper has summarized in detail the research progress in loess liquefaction controversial in the academic field and not adopted in active practice. It has also given a complete account of the research with loess liquefaction lab test by Prakash et al.,the field survey and analysis by Ishihara et al.on loess landslide disaster caused by earthquake liquefaction in Tajikistan. And the domestic strain and pore water pressure generation models gotten from lots of lab tests on loess liquefaction. The discussion and proposals for liquefaction criterion, microscosmic mechanism of loess liquefaction and field explosion experiment on loess liquefaction were emphasized. This paper gives several proposals for future research tendency.
