土动力学与岩土地震工程

Soil dynamics and geotechnical earthquake engineering

近年来,动力荷载引起的工程建设中的新问题给土动力学的研究不断注入新的活力,提出新的挑战,从而推动其发展和完善。文章简要回顾了土工动力测试技术、土体的动力特性与本构关系、土体液化、土石坝地震响应数值模拟、交通荷载引起的环境振动及长期沉降等方面的研究进展,并对一些需加强和深入的研究方向进行阐述。

In recent years, new problems in engineering construction induced by dynamic loading inject new energy and put forward new challenges to the research of soil dynamics, which also promote its improvement and development. This article presents a brief review on geotechnical testing technology, dynamic characteristics and constitutive relation of soils, soil liquefaction, numerical simulation of seismic response of earth rockfill dam, environmental vibration and long- term settlement induced by traffic loading and elaborate some areas needed to strengthen and further research.
