Optimization Analysis on Seismic Mitigation of Building Foundation in Coastal Area

The stability of the buildings foundation in coastal areas caused by the submarine earthquake caused by the seabed plate movement has increasingly become the research focus of the engineering construction department. For the foundation under special geological conditions in coastal areas, the failure mechanism is complicated and the stress analysis is difficult. Based on the current situation of seismic design of building foundation in coastal areas, and aiming at the immature aspects of seismic treatment of foundation in coastal areas, this paper analyzes the optimization scheme of seismic design of foundation in such areas, which provides reference ideas for seismic design of building foundation in coastal seismic zones in China. In this paper, the research method is mainly through the comparative analysis of the relevant coastal engineering foundation treatment cases, the comparison of their treatment schemes and the combination of the existing foundation damping theory to summarize the suggestions on the foundation damping design under the special geological conditions in China’s coastal areas. In this paper, it is suggested that two aspects should be considered in the design of foundation vibration reduction in coastal areas: the application of dampers to reduce the vibration of foundation structures and the reinforcement of rock and soil under the foundation to meet the requirements of vibration reduction.
