In this paper. Based on the data of laboratory test、Pressuremeter test and field loading test of Lanzhou's Loess-Like silt,the empirical relation between the modulus of deformation and the shear deformation modulus of pressuremeter, the empirical relation between oedome-tric modulus and pressaremeter modalos, and the empirical fomula for calculating the deformation modulus from pressuremeter test are proposed.
