Abstract:
The principal stress value and direction would be limited when the cyclic loading test was conducted with the common soil dynamic tests such as unidirectional dynamic triaxial test, bi-directional dynamic triaxial test. All kinds of complicated stress path could be simulated with the dynamic hollow cylinder shear apparatus. The dynamic hollow cylinder apparatus was the best equipment for studying the soil stress state caused by principal stress rotation. The complicated loading capacity had been verified after the constant principal stress deviation angle cyclic loading equation, the constant general shear stress value and principal stress rotation loading equation were deduced. Comparing the wave line peak of theory with the peak of test, the relative error is from 1.3% to 2.5%, which verifies that dynamic hollow cylinder sheer apparatus can simulate complicate loading. In order to simulating the soil element stress path caused by traffic loading, two equation were deduced that could simulate the complicate stress state induced by traffic loading. 22 figs, 10 refs.
