摘要
在已完成的土样径向变形数字图像测量基础上 ,实现了土样轴向变形和径向变形的同步测量 ,不仅可测量土样整体的平均变形 ,而且可测量土样的局部变形 ,还给出了图像测量系统的理论精度和实际测量精度。用砂土、粉煤灰两种饱和试样进行固结排水剪切试验 。
Radial and axial deformations are measured by digital image processing method(DIPM) and not only the average deformation of whole specimen but also the local deformation at different location of soil specimen can be obtained. The theoretical and real accuracy are given in this paper. At the end, local deformations measured at different section by DIPM and the average results by traditional method are compared.
