青藏高原冻土地区岩土工程研究进展与思考

The Advance and Review on Frozen Soil Geotechnics of Qing zang Plateau

我国青藏高原地区 ,广泛分布着性质极为特殊的多年冻土。近年来 ,随着国民经济建设、旅游业以及国防建设的发展 ,交通运输需求量的加大 ,许多工程建筑修筑于冻土地基之上。这不仅带来许多复杂的工程地质与岩土工程问题 ,同时也促进了冻土的开发和利用。主要总结了目前冻土在力学特性、地基处理以及环境变化等诸多方面的研究成果 ,指出了冻土研究的应用前景 ,对我国多年冻土地区工程的建设 。

The frozen soil has very special engineeri ng geological properties,which is widely distributed in the Qingzang plateau of Ch ina.Recently,due to the economic development, tourism, national defense construc tion and traffic increase, some construction has been constructed on the frozen soil.Therefore,most of the engineers have met the very complicated engineering g eology and geotechnical problems of frozen soil. The mechanics properties, groun d treatment and environment variation of frozen soil are summarized. It will be a good prospect of frozen soil research. It is useful to engineering constructio n in permafrost areas of China, especially to Qinghai Tibet Raiway.
