| 摘 要： | 冻土融沉系数是计算冻土融化后沉降量的重要参数,也是多年冻土融沉性分类的一个指标.本文根据345个冻土原状样品融沉压缩试验数据资料,对细砾土、砂土、粉土、粘性土、泥炭化粘性土和泥炭质土这六类土,分别得出了估计其融沉系数a0的回归分析方程.同时还简单论述了采用超塑含水量(w-wp)因子估计山区粘性土融沉性的效果及原因,分析...

| Abstract: | Thawing settlement coefficient is an important parameter for engineering design to estimate the thawing settlement of frozen soil and it is an index of thaw settlement classification of soil.Based on the 345 thawing compression test data of disturbed frozen soil samples,it gives out linear regression equations of six sorts of soils which are gravel,sand,silt,clay,peaty clay and peat soil.These linear regression equations can estimate thawing settlement coefficient of the soils.Meanwhile it makes analysis of... |
