Gate pier connection structure of marine construction in high seismic intensity region and construction method thereof

Abstract

The invention relates to a gate pier connection structure of marine constructions in a high seismic intensity region and a construction method thereof. Through the invention, no extra additional stress is produced in normal times and dynamic response and displacement of gate piers can be reduced during an earthquake so as to reach the objective of preventing the gate piers from being cracked and damaged. The technical scheme of the invention is that the gate pier connection structure of marine constructions in the high seismic intensity region comprises a gate pier foundation and gate piers poured at two sides of the gate pier foundation, and the gate pier connection structure is characterized in that a hyperviscosity fluid damper used for reducing the dynamic response of the gate piers is connected between the two gate piers. The gate pier connection structure of marine constructions in the high seismic intensity region and the construction method thereof are suitable for the treatment of a gate pier anti-seismic structure of marine constructions in the high seismic intensity region and can effectively solve the problems that the gate piers of marine constructions in the high seismic intensity region are easy to crack and break and influenced on safe operation, and the like.

Description

technical field [0001] The invention relates to a connection structure and a construction method of a gate pier of a hydraulic structure in a high seismic intensity area. It is suitable for the treatment of the anti-seismic structure of the hydraulic building pier in the high seismic intensity area, and can effectively solve the problems that the hydraulic building pier in the high seismic intensity area is easy to crack, damage and affect its safe operation. Background technique [0002] In the construction of reservoir dams in high seismic intensity areas, seismic design is a key technical issue. Due to the thin structure of the gate piers, which are mostly arranged on the top of the dam, the seismic response is strong, which is the weak link of the dam's seismic resistance. When an earthquake occurs, the gate pier will undergo rapid periodic vibration deformation due to the earthquake, which will generate a large dynamic tensile stress, resulting in cracking and damage at...

AI Technical Summary

Problems solved by technology

When an earthquake occurs, the gate pier will undergo rapid periodic vibration deformation due to the earthquake, which will generate a large dynamic tensile stress, resulting in cracking and damage at the bottom of the gate pier, which will affect the opening of the gate and endanger the safety of the project

[0003] At present, the aseismic design of gate piers usually adopts reinforced structural reinforcement. Although it can limit the development of cracks in gate piers, it cannot reduce the dynamic response of gate piers; if the top of gate piers is connected by a rigid structure, although it can reduce the dynamic response of gate piers , but the rigid connection load (including temperature load) is very large, and the structural design is very difficult
