摘要
采用数字图像相关分析方法，对砂土受均布荷载作用的全场位移进行了测试分析，并与传统的布辛奈斯克解计算结果相比较，得到了满意的效果．该法在连续体的位移场测量方面已有广泛应用，而用于主体的位移测量却少见，测得位移场后，再根据土的本构关系即可求得相应的应力场．这为主体模型试验中星测变形开拓了新的途径，也为岩土和地基工程的深入研究提供了一种更有效的方法．
The displacement field of sand underuniformly distributed load is measured by meansof digital image relative analysis, and the measuredresults axe compared with the Boussinesq's calcu-lationed ones. The result indicates that the test issatisfactory. This method is fiIst successfully ap-plied to the test of the displacement field of soil andis a new method in measuring deformation in soilmodel test, and is also a more effective means forthe study of geotechnical engineering and founda-tion engineering.
