摘要
综述了学术界有争议、尚未纳入现行抗震规范的黄土液化的研究进展,重点叙述了Prakash等的室内黄土液化试验、Ishihara等的对塔吉克境内黄土地震液化引起滑坡灾害的野外调查与分析等国外研究成果及国内由大量黄土液化室内试验得到的应变与孔压增长模型、液化标准的建立、黄土液化的微观机理及黄土液化的野外爆破试验、黄土液化与震陷的区别等,并对未来研究趋势提出了几点建议。
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.
