特殊土动力学的发展战略与展望

Development Strategy and Prospects for Study of Special Soil Dynamics

摘要:

在我国广泛分布的特殊土(包括黄土、冻土、新近堆积土和膨胀土等)具有独特、复杂的动力学性质和较高的致灾性,与之相关的动力学问题已成为工程界关注的焦点。本文在回顾特殊土动力学发展历史、近年来国内外主要研究进展及其发展趋势的基础上,展望了未来该研究领域的发展战略,提出了今后应重点发展的研究方向与课题。

Abstract:

The special soils, which includes loess, frozen soil, soft soil, and swelling soil, distribut widely in China, and are easy to cause disasters. For their particular microstructure, during dynamic loading the responses of special soils are unique and complicate. In recent yeas the dynamic problems of special soils have been the focal points in the field of special soils engineering. In this paper, the history and recent advance of special soil dynamics are reviewed. On this basis the future development strategy of the field is discussed, some study problems are put forward.
