本文提出了在寒区建筑物设计中,如何根据当地地基土的土质、地下水埋深及冻结期的负积温,利用当地野外试验资料所求得的经验公式,简便地预计建筑物地基土的冻胀量的方法。文中利用内蒙赤峰市宁城县甸子灌区野外冻账试验场的实测资料,推导出粘土、壤土在不同的地下水埋深及冻结期负积温情况下的冻胀量简易计算公式。可供水利及建筑设计、施工部门的技术人员参考。
This paper proposes how to estimate the frozen soil of building foundations based on the empirical formulas obtained from the local field test data based on the soil quality of the local foundation soil, the buried depth of groundwater, and the negative accumulated temperature during the freezing period in the design of buildings in cold regions. Swelling method. In this paper, using the measured data of the field freezing-depression test field in the Anzi irrigation area of Ningcheng County, Chifeng city, Inner Mongolia, the simplified calculation formulas for frost heave under different groundwater depths and negative accumulated temperature during the freezing period were derived. For water conservancy and architectural design, construction department technical personnel reference.
