应用三轴试样变形数字图像测量技术，对不同密度干燥和饱和状态的粉砂试样进行了三种围压条件下的三轴试验，通过对各种试验条件下的应力应变试验曲线的对比分析，从细观角度分析了围压、密度和孔隙水作用对粉砂试样变形的影响机理，得出了一些结论。

In this paper,with the triaxial digital image deformation measurement technique,silty sand specimens of different densities were tested with three different confining pressures under dry and saturated states. By comparing the stress strain results obtained from different testing condi-tions,the influences of the confining pressure,density and pore water on the deformation behavior of silt were investigated from a microscopic point of view,some results have been obtained.
