Li, H.; Wang, S., and Cheng, L., 2018. Dynamic characteristics numerical simulation of sea entrance soil under dynamic load. In: Liu, Z.L. and Mi, C. (eds.), Advances in Sustainable Port and Ocean Engineering. Journal of Coastal Research, Special Issue No. 83, pp. 1–5. Coconut Creek (Florida), ISSN 0749-0208.The traditional numerical simulation method of sea entrance soil dynamic characteristics has some problems, such as the low simulation value and the poor accuracy of the numerical simulation. In order to improve the above situation, a new numerical simulation method based on dynamic load is built. Through three steps of soil grid partition, finite element model establishment and load setting scheme selection, the finite element description of sea entrance soil dynamic characteristics is completed based on dynamic load theory. Through the three steps of dynamic characteristic numerical determination, simulation boundary condition determination and damping setting, the construction of a new numerical simulation method for the sea entrance soil dynamic characteristics is completed. The simulation application environment and design contrast experiment results show that compared with the traditional methods, the new method can completely improve the problem of low total numerical simulation and poor accuracy of numerical simulation.
