Abstract
The shore-approach sheet pile structure under integral load-relieving pile cap is a new shore-approach structure requires an available calculation method and the analysis of its mechanical properties.The study on the internal force distribution of the pile foundation and the improvement of structure design is worthy of engineering application.Based on a coastal heavy-piece wharf,an integrated CAD software was used to make a design plan,further study the stress characteristics and economy of the front and rear row piles under different pile diameters and longitudinal pile spacing.The results showed that the increase in the diameter of the rear-row piles had little impact on the bending moment of and the pressure acting on the front-row pile wall,significantly increased the bending moment of and the pressure on the rear-row pile foundation,and gradually reduced the horizontal displacement of pile foundation.In terms of the cost of pile foundation,large pile-diameter plan was recommended.It is necessary to carry out in-depth analysis of pile-soil interaction and the internal forces of upper structure in order to produce a more reasonable structure in the future.关键词
