摘要 基于全表面变形数字图像测量技术,采用干装法和湿装法制成了天然河砂及标准砂试样,并研究了两种试样在整个固结排水剪切(CD)试验过程中的变形规律,结果表明:试样在饱和、固结及剪切阶段均因制样方法的不同而表现出不同的力学特性;通过比较各个阶段密实度的变化发现试样密实度的变化并不是造成这种结果差异的主要原因。 Deformation in the process of Consolidation Drained shear (CD) test of the nature river sand and standard sand in various densities which made by Dry Tapping and Moist Tamping method has been studied by the whole-surface digital image measuring system. Results reveal that the specimens show the different mechanical properties by different sample preparation methods in the stage of saturated, consolidation and shear, the change of the density occurred in all the stages can91 be the main reason.
