建筑物基础受到不均匀的冻切力及法向冻胀力的作用,就会产生向上的隆起变形。当变形值超过允许值时,建筑物就会裂缝破坏。本文根据大量的试验研究资料及实践经验,分析了地基土的冻胀性,提出了基础埋深方法以及浅基础设计与施工应注意的一些问题。 The foundation of the building is subjected to an uneven chilling force and a normal frost heaving force, resulting in upward bulging deformation. When the deformation value exceeds the allowable value, the building will crack. Based on a large number of experimental data and practical experience, this paper analyzes the frost heave of foundation soil, and puts forward some problems that should be paid attention to in the basic buried depth method and shallow foundation design and construction.
