十字板剪切试验的综合应用

十字板剪切试验已广泛地用于测定饱和软粘性土抗剪强度,是求算地基承载力、围堤稳定、软粘土的灵敏度及固结历史等地基力学参数不可缺少的原位测试手段。本文根据十字板剪切试验的原理,结合临港工业区三期海域岩土工程勘察中对微型十字板、电测式十字板和机械式十字板的综合应用实践,提出了三种十字板剪试验的适用条件、优缺点和该地区十字板剪切试验指标综合应用的相应关系式。

THE vane shear test has already been widely used for determining the shear strength of saturated soft clay. it is a indispensable situate testing meansing in calculation the important mechanical parameters of foundation such as bearing capacity of foundation soil, slope stability analysis ,sensitivity of cohesive soil and consolidation history,etc.. This text based on the test principle of the vane shear test and combined the integrated application of miniature vane shear test, electrical -logging vane shear test and machinical-logging vane shear test in Three issues of industrial area bordering on the harbor for engineering geological exploration, and put forward the applicable condition of three kinds of vane shear tests , excellent place that lack and corresponding relational expression of testing integrated application in this area vane shear test
