摘要：

As a novel version of penetrometer, T-bar is extensively utilized in in-situ measurement for undrained shear strength of marine soft foundation. However, the effects of penetration velocity, anisotropy of soil strength and gradual softening on penetration resistance of T-bar penetrometer are seldom systematically investigated. The simple elastic-perfectly plastic Tresca model is modified to allow for the above mentioned effects based on the finite element software ABAQUS. Then the numerical simulations for penetration resistance mechanism of T-bar penetrometer in soft clay are conducted. The results show that the effects of strain rate, anisotropy of soil strength and strain softening on T-bar factor are appreciably large. Compared with the upper bound limit analysis, the present finite element solution is validated.
