寒冷地区地基处理方法——以甘肃省陇南地区农林工程项目为例

寒冷地区在地基施工方面的主要问题在于冬季在此类地区容易形成一定深度的冻土层,当气温变暖时,由于冻土消融带来的翻浆等问题,如果处理不当则会引起建筑物基础发生变形,引起建筑物的沉降以及产生裂缝,严重的会导致建筑物的倒塌。文章通过分析寒冷地区地基处理的方法,结合具体的工程实例,分析基坑支护时具体检测的要求及寒冷地区基坑支护的观测要点,提出寒冷地区大面积软土地基处理方法,为相关内容的研究提供参考。

The main problem of foundation construction in cold areas is that a certain depth of permafrost is easy to be formed in such areas in winter.When the temperature is higher,the frost will boil due to thawing and other problems.Therefore,if not handled properly,it will cause the deformation of the building foundation and the settlement of the building and produce cracks,which will seriously lead to the collapse of the building.Based on the analysis of the method of foundation treatment in cold area and based on specific engineering examples,this paper analyzes the specific detection requirements of foundation pit support and the main observation points of foundation pit support in cold area,and puts forward the treatment method of large area soft soil foundation in cold area,so as to provide reference for the study of related contents.
