The Inland River Beam-Slab High-Piled Wharf Upper Structure Prestressed Technology And Construction Technology Research

This thesis carefully analyzes and calculates the mechanics characteristics of the piled-beam wharf in the way of calculation of static and finite element numerical simulation.And it also uses the pressing technique in the super structure.It combines project cases to expounds the design and construction of the high-piling wharf in detail.It provides some reference of the technology of post-tensioned prestressing to the use of wharf design and construction.This thesis based on Chongqing Road Transport(Group)Co.,Ltd."Naxigou dock building key technology research projects",Chongqing Naxigou dock expansion project engineering as the basis for inland port in the Three Gorges Reservoir special hydrology,geology and terrain conditions,using the finite element software(Midas Civil)to establish a model after the introduction of Naxigou dock-tensioned optimized,taking into account the load change,water level changes and other factors,a lot of numerical analysis.The main results are as follows:(1)Exploratory relate post-tensioned prestressed and inland port,Complete the transformation of traditional pier to modern prestressed pier.(2)Put forward and summarized wharf monolithic beam of post-tensioned prestressed concrete design method and construction technology.(3)Put forward and summarized wharf monolithic five continuous girder(including track beam and ordinary stringer)prestressed concrete design method and construction technology.(4)To optimize the design of the Naxigou dock and remove the pier beam dependence on humanoid brace,increased the beam span from 8 m to 16 m.(5)To optimize the design of the Naxigou dock and remove the four stringer,implement stringer spacing increases from 3.2m to 5.33 m.
