摘要

在以往的研究中

由于受到三轴试样变形测量手段的限制

无法定量研究三轴试样的端部约束对试样受力变形及其测量结果的影响。采用数字图像测量技术

直接量测试样的轴向变形和径向变形

把它们与传统测量方法得到的变形测量结果进行比较

定量分析端部约束与端部接触对三轴试验土样的影响。同时笔者建议采用数字图像测量技术

直接测量三轴试样中间部分的土样变形

以此避开试样端部的影响

使试验结果更加真实可靠。

Abstract

Because of limitations of deformation measurement method。 it was difficult to research the in influences of soil specimen deformation caused by end restraint and end contact in triaxial test before. By digital image processing technique

the axial deformation and radial deformation of triaxial specimen are measured directly. Making a comparison between the results with traditional method and digital image processing technique

these influences are determined quantitatively. Finally

it is concluded that using the digital image processing method measure the local deformation directly can avoid the influence of the end restraint arid end contact to the deformation of soil specimen.
