Durability Analysis And Engineering Application Of Inland High-pile Wharf

Compared with conventional construction, because of the high-pile wharf is using in harsh environments, so its life is shorter. At present, most of the national terminal have been in service for decades, especially reinforced concrete structures High- pile of rusty been very serious, so research on the durability of high- pile has great significance. For high pile seaport durability predecessors have done a lot of research, because different inland terminals and port terminals of the environment, they suffered relatively little chloride ion erosion Seaport serious, high-pile wharf durability main river possible to analyze aspects of the load borne by the pier. Therefore, this article is based on two aspects of the inland high- pile durability studies, one study based on fatigue damage wharf member under cyclic loading, the second is to analyze the permanent load and variable load affect the reliability of the pier pile.Gantry crane load is one of the main loop pile wharf to withstand high loads, which is an important factor in dock construction material fatigue failure. Based on the basis of summarizing the previous research on the contents of this paper select the appropriate fatigue life calculation formula SN curve; research Miner linear fatigue damage accumulation principle and use cycle counting method of data compression, recognition machine loads go through the program Under stress cycle track beam; with specific examples with finite element software ANSYS high pile wharf door beams dynamic analysis. The power analysis, with related fatigue damage theory, the fatigue life of high-pile wharf gantry crane Beam and draw track beam fatigue life decreases with wheel pressure increases, while moving speed and load-independent conclusions.For damage characteristic pile under horizontal and vertical loads, the focus on the pile were analyzed two aspects of reliability: one pile on weight load and ship impact force under the joint action of the bending load Reliability analysis of bearing capacity; the second is the weight of the load and uniform load bearing capacity of pile grounds under the combined effect of reliability analysis. Through the study of the reliability indices of pile wharf pier provide reference of durability analysis.
