The Port of Sudan project is located under the special engineering geological environment of coral reefs.It is located in the excellent golden waterway of the World Red Sea.The shipping is extremely busy.On the basis of exploring the problems of the old port of Port Sudan,it is of great significance to use the construction technology of the construction of seaports and reclamation terminals in China.By studying the workability,mechanical properties and durability of Port Sudan under the coral reef geology,it is necessary to reveal the stability of the port under the influence of waves and earthquakes under special geological conditions.In order to understand the adaptability of solid blocks at home and abroad and caisson gravity harbor piers,sheet piles and high-pile structure wharfs,in the face of the development of the national port terminals along the Belt and Road,it is necessary to futher study the anti-wave impact of the harbor pier and the seismic power of the harbor pier.The mechanical characteristics of the response.Through the finite element numerical simulation analysis of the solid square and caisson gravity wharf modeling,the stability of the solid square gravity wharf and the degree of wave stability affecting the wharf are revealed.With the continuous duration of the earthquake,the overall movement characteristics of the solid square gravity stop berth deformed,revealing the dynamic characteristics of the seismic dynamic response of the solid square gravity wharf,such as the total velocity cloud map and the total acceleration cloud map.,shear strain vector distribution characteristics,effective stress vector characteristics and comparative analysis.In the analysis of the seismic characteristics of the dynamic gravity earthquake and the anti-wave shock seismic dynamic response,the distribution characteristics of the damage zone,seismic response displacement,velocity and acceleration duration are close to the actual engineering application.Through the analysis of seismic dynamic response characteristics of strong foundation caisson gravity wharf and strong foundation caisson gravity wharf against wave impact,the stability of the wharf is compared and analyzed.Combined with the analysis of seismic dynamic response characteristics of weak foundation caisson gravity wharf and weak foundation caisson gravity wharf against wave impact,the stability of the wharf is compared and analyzed.Through the comparative analysis of the anti-wave seismic response of the caisson gravity wharf,the new deep water high pier pier beam structure wharf and its seismic response and anti-wave shock seismic dynamic response analysis are studied.Taking the new port project of Port Sudan as an example,the finite element numerical model of the pier with high pier pier beam bridge was established,and the mechanical characteristics of the seismic response process were obtained.The simulation method of 3D plane pile unit in 2D plane strain problem is carried out,that is,the pile structure simulation in 2D plane strain problem,the assumption of 3D row pile unit,the parameters of 3D row pile unit and the 3D pile-soil interaction study Furthermore,the physical seismic dynamic response analysis of the high-deck pier-girder bridge structure,the seismic dynamic response analysis of the pile-pile body of the high-pile pier-girder bridge structure and the time-course characteristics of the seismic dynamic response of the high-deck pier-girder bridge structure are provided.The seismic dynamic response characteristics of high-deck pier-girder bridge structures are revealed.The seismic dynamic response analysis of the pier of the high-pile pier-girder bridge structure,the seismic dynamic response analysis of the pile-pile body of the high-pile pier-girder bridge structure,and the seismic dynamic vector field characteristics of the pier of the high-pile pier-girder bridge structure are carried out.With the continuous influence of seismic dynamics,the total displacement,total velocity and total acceleration vector field change,the high pier pier beam bridge structure has superior stability characteristics.As a mature structure type,the high-pile pier-girder bridge structure wharf is a mature structure type.Due to the special coral reef geology,further analysis reveals that the conventional design method cannot accurately calculate the various conditions under various complicated working conditions.The stress deformation of the quay-like structure and its seismic dynamic response mechanical characteristics,the research results can provide ideas for the engineering project,and also provide reference for the safety of similar projects.
