Moving Process Of Submarine Mudflow From Landslide Under Wave Loading

The submarine landslide is a very common Marine geological disasters. It causes serious deformation and fracture of seabed pipeline and it leads to the ocean drilling platform dumping. It even can cause serious earthquake and tsunami. The research of submarine landslide moving process is very important to prevent and reduce the marine geological hazards.This paper is based on the existing studies about analytical solutions of mudflow moving process. And it uses the perturbation method to calculate the analytical solutions of bingham mudflow generated by submarine landslide under the influence of the wave.It also uses the formulas of the obtained analytical solutions to analyse influence of wave about bingham mudflow moving process.The following conclusion can be reached:(1) It gets the formulas of the analytic solution of bingham mudflow under the influence of wave. These formulas can be used to calculate moving process characteristics of bingham mudflow under wave.(2) Relative to the mudflow movement,small amplitude wave has great influence on the moving process of bingham mudflow generated by submarine landslide. The wave slows the movement of mudflow. And the form of mudflow shows the characteristics of wavy rolling forward.(3) Different wave parameters have different influence on the moving process of bingham mudflow. The smaller the wavelength,the wave height and the greater the depth of the shallow are, the longer the bingham mudflow will move. Wave parameter has impact on moving process of submarine landslides mudflow by means of changing the size of the wave pressure.
