【摘要】 随着寒区工程,如青藏公路、青藏铁路、输油管道、西气东输等工程的日益增加,冻土的研究越来越深入,而力学问题是贯穿始终。本文从两个方面讨论冻土工程中力学问题的研究进展,(1)冻土受多种因素的影响,不能单一的用某一个条件解释,因此冻土水、热、力和变形的耦合问题已取得了长足的进展;(2)冻土路基受动荷载的影响非常显著,冻土的动力学性质的研究已全面开展。更多还原

【Abstract】 The research on frozen soil become ample along with increasing the cold region engineering constructions, such as Qinghai-Tibet Highway,Qinghai-Tibet Railway,Petroleum Pipeline,East-to-West Gas Pipeline, et al.It is sure that mechanics problems run through the research on frozen soil.In this paper,two aspects are mainly discussed about progress in mechanics problems of frozen ground engineering.One is the quiet great progress in coupling questions of water,heat,force,distortion,because frozen soil is influenced by many factors and the phenomena are not described by a certain condition;the other is the comprehensive study on frozen ground dynamics characteristics,because the frozen ground roadbed is observably influenced by dynamic loads.更多还原
