| 摘 要： | 对典型土料用零位移静力平衡法进行了法向冻胀力试验,并用数理统计方法分析和总结了法向冻胀力随试样含水量、饱和度和干密度等因素变化的规律。同时进行了标准冻胀率试验,建立了法向冻胀力与峰值冻胀率的关系,以及加荷固结稳定后荷载与冻胀率的关系。

| Abstract: | The paper tests the normal frost - heave force of typical soil by static equilibrum of zeros-lip,analyses and sums up a law that the normal frost - heave force of soil changes with the moisture content,saturation degree and dry density of sample, by mathematical statistics, tests the standard heave ratio, establishes the relation of normal frost - heave value with frost - heave ratio of peak value as well as the relation of loading with frost - heave ratio when conducting the loading maintenance. |
