Mechanical characteristics of the soil-structure interface in response to simple shear tests under constant stress increment ratio paths;

Applied with incremental theory, this paper has described a new approach for modulus of deformation varying with ratio of stress increment form the K 0 status.

Development of constant strain increment ratio path tests

The previous studies show that there exists a steady stress state,defined as asymptotic state,when sand is loaded along constant strain increment ratio paths.

The actual operational mechanism of multidimensional incremental route of agrarian route includes multifunctional replacement mechanism of agrarian resources,intensive mechanism of agrarian resources,establishing mechanism of agrarian resources and foreign input mechanism of agrarian resources.
