本文从土的内部结构的研究出发,对于最近十多年来土力学的几个基本理论的发展,作了综合性的报道;对于土的内部结构与力学性质之间的关系,提出初步意见,也指出今后研究的方向。综合报道并不包括近年来全部的主要成果,很多重要研究没有包括在内,因为它们不在本文所选定的这条线上。 In this paper, based on the study of the internal structure of soil, a comprehensive report has been made on the development of several basic theories of soil mechanics in the last decade or so. Preliminary comments have been made on the relationship between soil internal structure and mechanical properties. Also pointed out the direction of future research. The comprehensive report does not include all major achievements in recent years. Many important studies are not included because they are not on the line selected in this paper.
