Study On Cause Analysis And Carrying Capacity Of A High-pile Wharf Damage

At present, various types of wharfs are widely used in China. Most of these wharfs in use suffered some degree of structural damages for the following series reasons: design and construction, management operation, material itself deterioration by time, natural environment, and so on. At the same time, for the trend of ship maximization and wharf specialization, the proportion and function of the old wharfs could not meet the need of development.It is essential consquently to estimate the reason and degree of the damage,the carrying capacity of existing wharfe,to decide reinforce is needed and propose the safety operation measures.Based on a high-pile wharf project in Zhuzhou, the thsis carries out research work on the wharf including causes of wharf structure damage, finite element simulation of structure stress characteristics, damage simulation, and evaluation of carrying capacity. The main contents are as the following.1)The reasons for wharf damage and carrying capacity are analyzed systemly and comprehensively by collecting large number of documents.2) Wharf damage reasons are preliminary analyzed with methods of field test of the wharf combine the analysis of design, construction of wharf structure and operation management information.3) Build wharf sturcture model with the application of finite element method and calculate the force of the structure in normal load and over load conditions.Study the characteristics of wharf structure forces and analyze the causes of wharf damage.4) Using finite element method, simulate the wharf strctural damage,and build damage model. Then analyze the different force characteristics before and after damage, at meanwhile, assess the carrying capacity of damaged wharf. Therefor ,it can provide reference for the management and reinforcement of the structure in the future.
