Abstract

The invention provides a pier wave-making resistance reducer comprising a reducer body and a slide rail. The reducer body is of a nasal shape and comprises a nose part at the rear front, a nose bridge part at the upper front and a back part. The back part corresponds with the surface of a pier in terms of shape, and is connected with the pier through the slide rail in a vertical direction, and the reducer body is capable of moving up and down freely along the slide rail. The nose part is of a hollow structure, and the joint between the noise part and the noise bridge part is flush with the water level under effect of buoyancy. The pier wave-making resistance reducer is capable of effectively reducing water flow wave-making resistance and reducing impact to the pier from water flow so as to guarantee safety of the pier in the flood season.

Description

technical field [0001] The invention relates to the field of bridge structures, in particular to a wave-making resistance reducer for bridge piers. Background technique [0002] According to JTG D60-2004 "General Code for Design of Highway Bridges and Culverts", various loads and external forces acting on highway bridges are classified into three categories: permanent action, variable action, and accidental action. Among them, there are two effects related to water, namely the buoyancy of water and the pressure of flowing water. The buoyancy of water is a permanent effect, which is actually the static pressure of water; the pressure of flowing water is a variable effect, which is hydrodynamic pressure. [0003] The pier is on the interface between water and air. When the water flows, waves will arise on the interface (or free surface); on the other hand, water has a non-negligible viscosity. Therefore, solving the problem of the force of the bridge piers on the water invol...
