High-pile beam-slab wharf structure with rear supporting piles

Abstract

The invention relates to the technical field of wharf structures, and particularly relates to a high-pile beam-slab wharf structure with rear supporting piles. The high-pile beam-slab wharf structure comprises a high-pile beam-slab wharf structure body and rear supporting pile structures; and one end of each rear supporting pile structure is fixed to the rear edge of the high-pile beam-slab wharf structure body, and the other end of each rear supporting pile structure is embedded or buried in a slope protection structure of a river bank foundation. By the adoption of the structural arrangement, the rear supporting pile structures are arranged at the rear edge of the high-pile beam-slab wharf structure body to form an overall stress structure used for bearing the horizontal load of the wharf structure, and the high-pile beam-slab wharf structure can be arranged in offshore seaport and river port wharfs; and the use convenience of a wharf cannot be changed through the arrangement of the rear supporting pile structures, the area of a water area or a land area occupied by the wharf cannot be changed, and the problems that a traditional high-pile beam-slab wharf is poor in horizontal bearing capacity, high in pile foundation specification and large in number are effectively solved.

Description

technical field [0001] The invention relates to the technical field of wharf structures, in particular to a high-pile beam-slab wharf structure with rear support piles. Background technique [0002] The conventional near-shore high-piled wharf structure is mainly composed of mooring facilities, lower pile foundations, and upper beams and slabs. The design water depth at the front of the wharf is determined by the grade of the ship required to berth. The higher the grade of the ship, the higher the water depth requirement, resulting in an increase in the free length of the pile foundation at the lower part of the wharf. According to the principle of pile foundation bending, the increase in pile length has a greater impact on pile bending. The stability range decays exponentially. Therefore, for high-piled wharves that require large ships, the number of pile foundations and pile foundation specifications required for the wharf structure will increase significantly, which furth...

AI Technical Summary

Problems solved by technology

The design water depth at the front of the wharf is determined by the grade of the ship required to berth. The higher the grade of the ship, the higher the water depth requirement, resulting in an increase in the free length of the pile foundation at the lower part of the wharf. According to the principle of pile foundation bending, the increase in pile length has a greater impact on pile bending. The stability range is exponentially attenuated. Therefore, for high-piled wharves requiring large ships, the number of pile foundations and pile foundation specifications required for the wharf structure will increase significantly, which further leads to an increase in project cost and construction period.
