A NEW METHOD IN MEASURING THE SOIL DISPLACEMENT FIELD

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.
