原文全面论述了往返荷载下饱和砂土的强度、液化和破坏问题,建议以极限平衡理论作为评定饱和砂土在地震往返荷载下开始破坏的准则,并提出了相应的分析方法。这对于深入了解液化问题的实质是很有意义的。下面提出几点补充和讨论意见:
The original article comprehensively discusses the strength, liquefaction and failure of saturated sand under cyclic loading. It is suggested that the limit equilibrium theory be used as the criteria for assessing the damage of saturated sand starting from a seismic back-and-forth load, and a corresponding analysis method is proposed. This is very meaningful for understanding the essence of liquefaction. Here are a few points to add and discuss:
