摘要
采用干装敲击法与湿装夯击法两种成样方法,制备了三种典型砂土的中密状态饱和试样,并利用应变控制式静力三轴仪进行固结不排水剪切实验,比较分析了成样方法对各砂土应力应变关系及抗剪强度指标的影响,实验结果表明:成样方法对试样的应力应变关系及抗剪强度指标有显著影响,但成样方法对不同砂土影响程度不同。
A set of Consolidated Un-drained triaxial tests were conducted on three kinds of sands prepared by dry-rapping method and moist-tapping method controlling the same density. The comparative analysis of stress-strain relationship and effective shear resistance index of specimens prepared by different methods show that specimen-reconstituting method have a significance impact on the stress-strain response and effective resistance index of sand,but the influence of specimen-reconstituting method differ by the type of sand.
