适筋化拱型桥面连续结构设计与分析OA

At present,the industrial construction of highway bridges uses prefabricated concrete beam bridges on a large scale and adopts simple supported bridge deck continuous structures.This research aims to improve the durability of the continuous bridge deck structure,comprehensively considers construction convenience and economy,and proposes a new type of bridge deck continuous structure.In this paper,ANSYS numerical simulation method is used to establish a solid finite element model of T-beam and bridge deck continuity,and through comparative analysis of forces under nine working conditions such as lane load,temperature effect,and uneven settlement of adjacent piers,the advantages of the reinforced arched bridge deck continuous structure compared with the rigid connected bridge deck continuous structure are verified.The innovation of this research is that based on extensive investigation of the difficulties and difficulties of continuous bridge deck construction,the project team designed a new bridge deck continuous structure with appropriate reinforcement can better adapt to the beam end structure commonly used in prefabricated beams and slabs in actual projects.At the same time,it improves the problem of continuous over-institutionalization of arched bridge deck,and the project cost is low,providing bridge engineers with a design plan for a new bridge deck continuous structure.
