摘要
据寒期观测采集的长春南湖湖岸露基船台"冻拔"位移数据建立的位移曲线,分析气温变化和船台基土冻胀对船台冻拔的影响,揭示露基船台的"冻拔"规律。
According to the freezing-pulling displacement data of Changchun south lakeshore exposed base berths observed and collected during the frosty period,the change curve of the displacement has been crea-ted,which analyzes the influential facts to berth freezing-pulling by temperature changing and frost-heaving berth soil.Finally,the freezing-pulling laws of the exposed base berths have been revealed.
