- Abstract:
- In this paper,the seismic responses of the structure foundation breakwater are analyzed and calculated using the finite difference software FLAC3D,including the emphasis on the degree of foundation liquefaction and deformation.Calculations results show that:under the strength of the smaller earthquake conditions,the breakwater structure foundation analysis is a smaller extent of the damage,and can be used normally; In the role of a strong earthquake conditions,breakwater structure can be liquefied at part of the foundation.There have been obvious changes in pore pressure and displacement variations.When the peak acceleration exesses 0.2 g the structure foundation is liquefied,Breakwater structure is a clear foundation liquefaction phenomenon,Liquefaction areas are mainly concentrated in the upper right side of the structure.Deformation of breakwater under the seismic action has a relatively small impact on overall structure safety,and the main influence factor of the security is sandy soil liquefaction which will damage structure to varying degrees.The research results on this paper can provide reference for seismic design of similar projects.
