| 摘 要： | 本文应用激光散斑法对成都裂隙性粘土的变形特性进行了研究,得出这种土的变形性受其本身裂隙数量、倾角大小、裂隙中隙壁粘土量的多少以及尺寸效应等的控制。通过全场测试,得到了普遍常规试验对粘土无法直接测得的参数——泊松比及土表面各点的位移分布。

| Abstract: | In this paper, laset speckle int erferometry is applied to study characteristics of Chengdu clay deformation. The de-
formity of this clay is related to quantity of fissures and slope angle size of itself, etc.. Through all-spot measuring we
have got the parameters of clay: poisson's ratio and displacement distribution of clay surface which can not be directly
obtained by conventional tests. |
