前言虽然从土力学发展成为一门科学时起,人们基本上就认识和了解与土的某些临界状态有关的基本现象,如“液化”或“敏感条件”等,但只是近十五年才致力于开展地震时土的动力反应的各种机理的物理本质的研究。特别是许多研究者主要通过广泛的室内试验,用小尺寸试样集中研究了循环荷载对

Foreword Although from the time when soil mechanics developed into a science, people basically understand and understand basic phenomena related to certain critical states of soil, such as “liquefaction” or “sensitive conditions,” but only Fifteen years have been devoted to the study of the physical nature of the various mechanisms of the dynamic response of earth during earthquakes. In particular, many researchers have mainly studied cyclic loading pairs using small-size specimens, mainly through extensive laboratory tests.
