摘要
在已有研究的基础上,简要地分析东北地区土地的冻胀融沉原理。以长春地铁5、6号线冬季施工监测数据为样本,系统分析长春市区域在季节性温度变化条件下冻胀、消融对土质地层的影响规律,并归纳了冻胀和融沉对土质地层的影响,分析了沉降测点处冻胀和融沉造成的地面隆起和沉降以及冻融水位的变动周期。
On the basis of existing researches,the frost heave and thawing setelement principle of soils in northeast China is briefly analyzed.Taking winter construction monitoring data of Changchun Metro Line 5 and 6 as samples,the influences of frost heaving and thawing settlement on soils in Changchun City under seasonal temperature changes are systematically analyzed,the influence laws of frost heaving and thawing on soils are summarized,and the ground surface settlement and heaving caused by frost heaving and thawing at measuring points as well as the variation period of freeze-thaw water level are analyzed.
