自1964年日本新泻地震和美国阿拉斯加地震之后,日本、美国等国家广泛地开展了对饱和砂土的液化研究。我国汪闻韶早在1962年曾发表过关于砂土液化问题的论文,并于1974年又发表了关于饱和砂土在往返荷载下极限平衡破坏准则的文章。因此,相比之下,饱和砂砾料的试验研究则比较少。1975年,我国海城地震时石门水库坝身砂砾料滑坡,及1976年唐山 Since the 1964 Niigata and Japan earthquakes in Japan, Japan, the United States, and other countries have extensively conducted liquefaction studies on saturated sand. China’s Wang Wenqi published a paper on sand liquefaction as early as 1962, and in 1974 published an article on the principle of ultimate equilibrium failure of saturated sand under cyclic loads. Therefore, in contrast, the experimental study of saturated sand gravel is relatively small. In 1975, when the Haicheng earthquake occurred in China, the gravel material landslides of the Shimen reservoir dam and the 1976 Tangshan
