摘要
对三种典型土料进行不同含水量、饱和度和干密度条件下的一系列闭式冻胀模拟试验。研究了土的η-w、η-γd关系,并对其进行线性分析,得出试验土料的冻胀规律。根据所得η-w关系式,得出各种土料相应于各冻胀性分级的界限含水量值。进而分析各种土料的冻胀敏感性,并与有关文献进行了对比分析。
According to the test results of closed simulated frost heaving experiments on three kinds of different typical soils in the infuence of different water contents, saturations and dry density, analyzed the relationship of the η-ω, η-rd curves of soil, and open out the frost heaving law of soils. Moreover, educe the limit water content value relatives to each classification for frost heaving, and also thc frost heaving suscepti- bility of each soil, and then compare them with the literature related to.
