用双桥静力触探计算粘性土承载力的经验公式

Empirical Formulae for Calculating Clay Bearing Capacity with Double-Bridge Tactile Impression Exploration

通过双桥静力触探资料与钻探资料的对比,提出了侧壁阻力与一般粘性土的塑性指数及液性指数的关系,在此基础上,统计出利用双桥静力触探资料确定一般粘性土承载力的经验公式.

Comparing the information of double-bridge tactile impression exploration with that of drilling,author presents the relation between the plastic index and liquid index of side-wall friction and common clay.On this basis,the empirical formulae for determining common clay bearing eapacity are conclued by means of the statistical infor- mation of double-bridge tactile impression exploration.
