is proposed,based on the characteristics that the rise and fall with the tide level of a ship aground on single point appear as vertical rise and fall of the tide level at the grounding point.

This essay has focused on the refloatation of single point grounded vessel.

Discussion on how to effectively prevent ship grounding in the Jingjiang Reach

Accidents of ship grounding will cause such disasters as ship hull damage, environmental pollution, lost lives and so on.

The explicit nonlinear finite element analysis has gradually become an important method in dealing with the ship grounding problem,in which the modeling technique is the key to the numerical simulation.

The means of the emendation,checkback and evaluation of the stability of worships in many complex points are discussed in this paper,which may supply some references for the engineering personnels of rescue and salvage and the crew of the worships that have run aground when they emendate and check the stability of the wreck.
