Abstract:For obtaining the exact mechanical parameters of marine layers,a new method was proposed based the pressuremeter test,its difficulty and the corresponding solution were also described clearly. The method for calculating design parameters from pressuremetertes was modified using the in situ contrast experiment on the land. Furthermore,the results from pressuremetertes in the sea were also compared with that ontained from vane shear test and standard penetration test. The research results can provide the calculation method for the marine structures foundation design on one hand,and can rich marine strata exploration methods on the other hand.
