渠基粗、细粒土的冻胀性分类研究

Study on the Classification Index of the Frost Heave of the Coarse and Fine Grained Soil Canal Site

渠基土与工民建地基土比较,由于渠基土经常处于饱和状态,与工民建地基土所处情况不同,其土的冻胀性分类:粗粒土要考虑其可能出现的冻胀性;细粘土则要增加一个土的密实度控制指标。文中仅就这两个问题进行讨论并进一步作出定量分析。

Make a comparison between the canal base soil and the industry civil builing base soil, owing to the canal base soil often be in saturated state, the canel base soil and the indastry civil building buse is different the frost heave of the xlassifiestion of the canel base soil is the situntion of the coarse soil ,we must thiak over possible the frost heave to appaar .On the stiuation of fine grained soil we must increase density of soil and coatrol the target .These two question are disscussed and analysed quantity furtater in this article.
