Problem of effects of seafloor silt on earthquake action environment of ocean engineering

The problem of effects of the Theological behaviour of seafloor silt on earthquake action environment of ocean engineering is presented and some discussions are done in this paper. Based on the experimental results of the rheological characteristics of seafloor silt1'1 (the seafloor silt is a Bingham body) and the theoretical results in relation to the unsteady laminar flow of a viscous fluid layer of Finite thickness over a plate(2,3), the response analysis method for a layered system which consists of sea water, seafloor silt and bearing soil under seismic disturbance is introduced, and a numerical example of a system composed of a silt layer in viscous fluid state and bearing soil layers beneath it is given.
