Problems solved by technology

However, at present, the calculation of the overall wave force of this type of foundation is not involved in the bridge design code. Most of the built sea-crossing bridges have measured the overall wave force on the bridge foundation through physical model tests. However, the disadvantage of this method is that the test period is long. The overall cost is high, and the general guiding significance is insufficient

Embodiment Construction

[0057] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0058] see figure 1 As shown, the embodiment of the present invention provides a method for calculating the wave force on the foundation of a sea-crossing bridge. One end of the foundation 1 is connected to the seabed, and the other end is provided with a cap 2. The cap 2 is an integral structure, and the cap 2 is connected to all the single piles 11. The top of the cap 2 is provided with a pier 3, and the size of the pier 3 is smaller than that of the cap 2. ;

[0059] Calculate the wave force on pile foundation 1, cap 2 and pier 3 respectively; and obtain the relationship between the wave force on pile foundation 1, cap 2 and pier 3 and the wave force on the bridge foundation through the model test method phase coefficient, and calculate the wave force on the foundation of the cross-sea bridge

[0060] Such as figure 2 As shown, the pie...

Abstract

The invention discloses a method for calculating wave force borne by the sea-crossing bridge foundation and relates to the field of bridges. The sea-crossing bridge foundation comprises a pile foundation, a bearing platform and a bridge pier, wherein the pile foundation comprises a plurality of single piles, one end of the pile foundation is connected with the sea bed, and the bearing platform is arranged at the other end of the pile foundation; the bearing platform adopts an integrated structure and is connected with all the single piles, and the bridge pier is arranged at the top end of the bearing platform; the bridge pier is smaller than the bearing platform. The method for calculating the wave force borne by the sea-crossing bridge foundation comprises steps as follows: calculating the wave force borne by the bridge pier; calculating the wave force borne by the bearing platform; calculating the wave force borne by the pile foundation; calculating the wave force borne by the sea-crossing bridge foundation. By means of the method for calculating the wave force borne by the sea-crossing bridge foundation, the overall wave force borne by the sea-crossing bridge foundation can be more simply and conveniently calculated, and the problem that the overall wave force borne by the sea-crossing bridge foundation comprising the bridge pier, the bearing platform and pile foundation in sea-crossing bridge engineering cannot be calculated is solved.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a calculation method for the wave force on the foundation of a cross-sea bridge. Background technique [0002] In recent years, the construction of cross-sea bridges in my country has developed rapidly. The East China Sea Bridge, Hangzhou Bay Bridge, Hong Kong-Zhuhai-Macao Bridge, and Pingtan Strait Highway-Railway Bridge have all become world-renowned super projects. Sea-crossing bridges are also gradually developing from the offshore to the open sea. The hydrological environment is becoming more and more complex, often featuring deep water, large waves, and rapids. The wave force on the bridge foundation has also become a controlling load for structural design. [0003] In order to reduce the wave force on the foundation as much as possible, the foundation forms of pier-cap-piling foundation are widely used in sea-crossing bridges. However, at present, the calculation of the ...
