摘要

融沉变形破坏是多年冻土区建筑物冻害的主要原因之一，实际的融沉量是热融沉陷与压缩沉降量的叠加：冻土融化体积压缩系数是估算冻土融后压缩沉降变形量的关键计算参数。根据286个冻土原状样融沉压缩试验数据资料，对细砾土、砂土、粉土、黏性土、泥炭化黏性土和泥炭质土等6类土，分别提出了在0～100 kPa和0～200 kPa压力段两种条件下的体积压缩系数和干密度之间的线性、二项式和对数式回归分析方程式。在此基础上，给出了确定6类土体积压缩系数的经验数据表。此外，还指出了现有规范推荐方法和建议值所存在的问题

Abstract

Thawing settlement deformation is one of the main freezing damage for the structure in permafrost region. The actual thawing settlement is the superposition of two parts: thaw settlement and compression settlement. The volume compression coefficient is the key calculation parameter in estimating the compression deformation. Basing on the 286 thawing compression test data of undisturbed frozen soil samples

it has put forward various types of regression equations including linear equation

binomial equation and logarithmic equation and these equations represent the relationship of volume compressibility and dry density of six sorts of soil on the two different pressure sections 0−100 kPa and 0−200 kPa. These soil types are fine gravel

sand

silt

clay

peaty clay and peat. On this basis the empirical volume compression data table of the six sorts of soils is given out; meanwhile

the problems in recommended methods of specifications are pointed out.
