摘要
本文根据粘性土和细砂的冻胀性与不同埋深基础的冻胀试验,对季节冻土区桥涵基础埋深的影响因素,如标准冻深修正系数、容许残留冻土层厚度及基础埋深对冻深的影响系数等进行了分析,提出了公路桥涵基础最小埋深的计算方法与参数。
Based on the experiments on the frost heave susceptibility of clayey
soil and fine sand and the frost heave tests under different depths of foundations,the
factors influencing the depth of bridge and culvert foundations in seasonal frost region
including correction of standard frost penetration,the allowable thickness of frozen
soil beneath foundations and the correction of frost penetration according to the depth
of foundations are analysed in detail in the paper.A method and its related parameters
for the minimum depth calculation of bridge and culvert foundations are also present-
ed in the paper.
