[Abstract]
Acco rding to the basic calculation st ructur e of a ship lock head on the soft foundatio n, a thr ee2dimensional finite ele2 ment model of lock head and foundation was developed using finite element software ABAQUS. The stress distributions of elastic model and elastoplastic model under the same w orking condit ions w ere calculated and analyzed. The tensile stress of the reinforced model was calculated. Finally , the reinfo rcement effects w er e ver ified based on the calculation results and relev ant fo rmula.
