室内土动力测试研究进展
|
摘要
对主要的室内土动力测试仪器及其特点进行总结;指出室内土动力测试的研究方向与重点是试验研究材料的扩大与延伸、复杂应力状态下土动力特性研究、小应变下土动力参数的求取、土的动强度和液化及动力参数影响因素的探讨4个方面;对动强度与液化基本概念作了较深入的探讨;指出目前已提出的动本构模型主要有黏弹性、弹塑性和内时动本构模型3类,其中在土体动力分析中应用最广的是等效非线性黏弹性模型.
The main instruments for soil dynamic indoor tests and their characteristics were summarized. The trend of and some key points in their development were presented, i.e. the expansion of test materials, research of soil dynamic properties under complicated stress state, acquirement of soil dynamic parameters under small strains, and some influencing factors on dynamic intensity, liquefaction and dynamic parameters. The basic concepts of dynamic intensity and liquefaction were further discussed, and some advances in the dynamic constitutive model were also reviewed.
