Study On The Inland Port High-Cut Bank Slope Bank-linking Type And The Relationship Between It And Wharf Structure

With the Three Gorges Reservoir storage,Chongqing urban port is a completely fluctuant backwater area of Three Gorges Reservoir, water level luffing bigger than 30m, water depth greater than 40m,terrain undulating,geological more bare rock, bank-slope steeper, and so on.The conditions make the dispose of bank-linking structure of the piled wharf more complicated in this region. Therefore, with Inland water depth deep, water level luffing big, shore-slope steep, free length of wharf structure long etc. Studying on the inland port high-cut bank slope bank-linking type and the relationship between it and wharf structure, which improves applicable ability of bank-linking type and has the important practical significance.According to Chongqing Highway Transportation Company"Naxigou wharf key technology research project": reconstruction wharf project of Naxigou in chongqing, aiming at the inland port special hydrological, geological and topographical conditions,this paper establishes interaction model between high-cut bank slope bank-linking and front wharf structure, considering the factors such as construction , load change during operation and water level variation. A large amount of numerical analysis research clear out effects of these factors for interaction between bank-linking and front wharf structure. Through compared analysis the interaction result of the different bank-linking type ,we draw that:Interactions of bank-linking type and front wharf mainly embodied in back row piles and bank-linking structure under no interactions of bank-linking type and front wharf.So, for the bank-linking type,we can design front wharf and back bank-linking type separately, adopting measures to reduce their deformation.Existence of a simply-supported board makes it bigger reaction between front wharf and bank-linking structure and more complex .When it is designed, we should overall consider, integration design.It's adding damping device between bank-linking and wharf structure that eases level force produced by back filling and heap load.Aiming at the outstanding problems of interaction of the above two bank-linking types, this paper puts forward different types of optimization scheme, providing the basis for the future wharf design.
