南水北调西线工程调水区冻土特征

The Traits of the Frozen soil in the Western Line engineering area of Diverting Water from South to North

冻土的存在 ,不仅会对建于该区的建筑物造成危害 ,而且还可能引起塌滑、泥 (石 )流、地面融陷等不良地质现象。本文从分析影响冻土发育的因素入手 ,分析了调水区的冻土类型和分布规律 ,以及冻土的构造及工程地质特征 。

The existence of frozen soil not only do harm to the building in the area but also cause collapse and avalanche,subsidence and other unfarvorable geologic phenomean.Beginning with analyzing facfors which affect the developement of the frozen soil,this paper analyzes the type and distribution regularity of the frozen soil,and its structure and engineering geologic traits and finally simply forecasts the frozen soil's developing tenctency.
