On formation of diseases on roadbed in many-year frozen soil areas in Heilongjiang Province

以黑龙江省冻土区公路工程为例,对纵向开裂、路基融沉、边坡冻融松散、冻胀和冰丘等常见病害进行了机理分析,旨在为黑龙江省多年冻土地区道路的养护与维修提供理论参考。

Taking the road projects in frozen soil areas of Heilongjiang Province as the example,the paper analyzes the mechanism for the diseases including the longitudinal craze,roadbed melting and settlement,loose frozen of slopes,frost heave and ice mounds,so as to provide some theoretic reference for the maintenance of the roads in frozen soil areas in Heilongjiang Province.
