【摘要】 综述近３０年来国内外有关砂土液化及液化后分析方法的主要科研成果，叙述由Ｓｅｅｄ等人发展起来的砂土液化分析的总应力法和由Ｍａｒｔｉｎ等人发展起来的有效应力法，对各种方法的优缺点进行比较，并认为今后在液化的判别方法、液化时固相与液相转换机理、骨架与水相互作用、液化时的大位移与大变形问题、土体液化后特性及液化后土体破坏机理和破坏过程、震后再固结体应变变化规律、不规则荷载下砂土的液化特性及影响孔压变化的地震波序的主要控制参数等各方面问题有待于进一步研究。更多还原

【Abstract】 Some major results of the study on analysis methods of liquefaction and post liquefaction of sand both at home and abroad in the past 30 years are reviewed in this paper,and examples of total stress analysis methods by Seed et al.and effective stress analysis methods by Martin et al.about sand liquefaction are given.Some advantages and disadvantages of these methods are compared.Finally,it is pointed out that the liquefaction and post liquefaction behavior of sand during earthquake is a complicated problem,and needs further studies.更多还原
