Structure Design And Analysis On Pile Foundation Of High-piled Wharf

The high-piled wharf is widely used in engineering because of its good adaptability to soft soil foundation.High-piled wharf is a spatial structure,which has the characteristics of spatial stress,it is more appropriate to be calculated as a spatial structure.But In general,the internal force calculation of high-piled wharf is carried out in the vertical and horizontal planes separately,that is,the horizontal bent frame is calculated as the flexible pile platform and the longitudinal bent frame as an elastic support continuous beam.The error of the calculation result is not very big,and safer,so it is acceptable.At present,the calculation of high-piled wharf structures mostly uses plane finite element analysis methods.Using the visualization interface can input the data and design conditions quickly and easily,which makes the data entry and calculation efficient and accurate.The software can automatically distinguish the Partial coefficient for Loads of various properties according to the standard criterion and find the leading load and use a different combination of formula under different conditions.The software can give bending moment,shear and axial force envelope diagram drawing automatically according to the calculation results of the component.It is easy to use and to understand.But above-mentioned software cannot consider the horizontal force along the pier longitudinal bents(such as the tube thrust).Due to the increase of Petroleum Chemical Wharf in recent years,in order to study the influence of thrust force on pile foundation,It is necessary to conduct a careful study by using a general finite element program to compare and analyze the calculation results of the calculation software of the horizontal trusses of Fengji PJJS Wharf with the calculation results of the general finite element program.it is also necessary to study the error and usability of using universal computing software for internal force calculation of pile foundation.We take Changxing Island Hengli oil wharf as an example In this paper,calculate the internal force of pile foundation for the platform and mooring pier using Fenghai PJJS pier lateral row frame software structural software respectively,and make an analysis and comparison between the results and draw an empirical summary and give the error and availability for using general software in the calculation of internal force of pile.This paper can be used as reference for the structural design and internal force calculation of wharf and can provide experience and reference for other wharf construction.
