Antiseismic Optimization Design Of Three Gorges Reservoir Area High-piled Frame Wharf

The earthquake is one of the most harmful disasters in nature. Seismic hasenormous destructive to the wharf structure. It is also one of the most importantdynamic loads in structure design. These years, on the inland rivers, especially onthose as Chuan-Jiang river stretch of the Yangzi River, vertical wharf is widely used.However, the structure of vertical wharf is complicated and changed on the differenthydrogeological conditions, so its dynamic and anti-seismic property are different and.Currently, the design theory and method are lagged behind the engineering practice.Besides，China is one of those countries which have serious earthquake disaster, andthe west areas are in the Euro-Asia seismic belt.So based on the ground above and the West Comunication program “KeyTechnology Study of Overhead Vertical Inland Wharf”, this article summarized thestructural anti-seismic method and their properties home and abroad, and theanti-seismic study about overhead vertical frame wharf with great water difference onInland River at present stage. To address the property of overhead vertical wharf,based on the Chongqing port Guo-Yuan container Terminal Phase2Project, the finitesoftware “ANSYS” are applied to analyze its modal to get its dynamic property andthe response spectrum analysis with3direction vibration is used to get its dynamicresponse to seismic. All the work above is showed that the anti-seismic property ofGuo-Yuan container Terminal Phase2Project is well. Based on the work before, theoptimization method of frame wharf is put afward. Combined the structuraloptimization design theory and “ANSYS-APDL” language, the whole quality of thestructural as the goal function, and the seismic response as the constraint condition,the optimization design and its static analyze has been done to verify its applicability.
