目前,在土建工程基础的设计中,为了在现场获得土壤切向冻胀力或法向冻胀力资料,最好是按设计基础的尺寸、型式和埋深(法向冻胀力基础)进行直接测定。若设计基础的尺寸过大,不能直接测量时,可用与设计基础相似的小尺寸基础测量,然后换算成大尺寸基础的冻胀力;或根据邻近相似地区同种型式、材料、埋深基础的观测成果,换算设 At present, in the design of civil engineering foundations, in order to obtain the data of the soil tangential frost heave force or normal frost heave force in the field, it is best to carry out the design based on the size, type and depth of burial (normal frost heave force basis). Direct determination. If the size of the design basis is too large and cannot be directly measured, a small-size basis similar to the design basis can be used to measure and then converted into a large-size basis frost heaving force; or based on similar types, materials, and deep foundations of adjacent similar areas. Observations, conversions
