Test And Finite Element Analysis For The Xiangtan Vertical Type Wharf

With rapid development of water transport, port construction in our country is growing. Because of the rapidly increasing throughput of the ports and the impact of large-tonnage vessels, many ports are into "overload" state in recent years. In addition, with unusual climate, frequent natural calamity and the ports’external environmental deterioration, the damage and destruction to existing ports is of increasingly serious, which have a big potential safety problems. Therefore, the comprehensive detection and safety evaluation research of the port has positive theoretical meaning and engineering application values.Taking the Xiangtan vertical type wharf (XVTW) as the research object, test and finite element analysis for the port are carried out, and the comprehensive service performance of the wharf are evaluated in this paper. The main contents of research are as follows:1.The comprehensive detections for the XVTW including appearance inspection of cap, foundation piles and bulk yard, and the inspection of concrete strength, the concrete cover thickness, the steel corrosion and the deck diseases are completed. Through the inspection, complete testing data can provide reference for the finite element analysis.2. By using general finite element software ANSYS, the space analysis model for the wharf is set up, in which loads are applied and reasonable boundary conditions are considered, and strength, stiffness and stability of the wharf are analyzed. The results show that under various loads, settlement of port, the maximum tensile stress, maximum shear stress all satisfy requirements.3. The measured results of static loading test for the structure are basically in agreement with the calculation results obtained by ANSYS. Displacement and stress at the control points under different loads are less than the allowable specification value, and the wharf bearing performance meets the design requirements. Displacement and strain recoveries are good after removing loadings. It shows that the wharf elastic performance meets the design requirements.4. Dynamic loading test reflects that the dynamic properties are good. There are no major structural defects in the wharf.
