目前,大多数关于液化问题的室内试验研究仅局限于对土单元体在不排水条件下动力特性的探讨,而很少注意到实际中广泛存在的成层地基的不同影响。本文介绍可液化土层处于成层地基中不同层位时液化发展过程特性的试验成果,以便提高对成层地基液化势定性评价的准确性。 At present, most of the laboratory experiments on liquefaction problems are confined to the discussion of the dynamic properties of soil unit bodies under undrained conditions, and little attention has been paid to the different effects of layered foundations that are widely present in practice. This paper describes the test results of the liquefaction development process when the liquefiable soil layer is in different layers in the layered foundation, in order to improve the accuracy of the qualitative evaluation of the liquefaction potential of the layered foundation.
