摘要
应用K0侧压力仪对天津市浅层土进行了不同试验条件下的K0系数室内测定,并对它的分布及变化规律作了分析.经研究得到天津市浅层土典型剖面K0分布图式,K0系数与各土层物理性质关系统计表.对在不同试验条件下的K0系数与土的塑性指数Ip之间的关系进行了满意的数据拟合,同时阐明了各种试验条件下的K0值在岩土工程勘察中的应用.
The at-rest lateral earth pressure coefficient_K0, was studied for shallow soils in the Tianjin area, using the auto-graphic K0-meter, comprising K0-values under different conditions; presenting the analyses of their variation and distribution pattern. Through these tests and analyses, It was obtained that the distribution patterns for K0-values of type protiles and the statistical chart of the physical norm for each soil level of over 25 meters and K0 -coefficient. A satisfactory match was given between the K0 -coefficient and plasticity index of soils (Ip). It was shown how to use K0-coefficient under different conditions in geotechnical engineering.
