Filling type concrete shell plate arch bridge

Abstract

The invention provides a filling type concrete shell plate arch bridge. The filling type concrete shell plate arch bridge is an innovative bridge type structure of a masonry arch bridge and has the advantages that material obtaining is easy and convenient, the force is reasonable, the manufacturing cost is low, and the application range is wide. Based on original computational examples, brief introduction PPT slides and a WORD manuscript of the filling type concrete shell plate arch bridge are further summarized and supplemented from the aspects of structural sketches, force principle analysis, section calculation methods, side wall stability checking, material strength design indexes and the like. 'Five different' and 'five first' of the bridge type are outstandingly reflected, specifically, 'five different' comprises that the structures are different, materials are different, the force is different, calculation methods are different, and construction is different; and 'five first' comprises that the stabilized soil materials are used for the bridge structure for the first time; the stabilized soil materials are proposed to be used for bridge structure strength calculation indexes through tests for the first time; the masonry composite system arch bridge is designed for the first time, and a series of internal force and section strength checking is conducted; the calculation method for an arch building to participate in calculation of the force of a main arch ring is put forward for the first time; and related formulas of a 'stabilized soil-reinforced concrete' composite structure to conduct section strength calculation according to a reinforced concrete structure section calculation mode are deduced for the first time.

Description

[0001] 1. Technical field Innovative structural design of masonry arch bridges 2. Background technology [0002] According to its static system, arch bridges can be divided into 'simple system arch bridges' and 'combined system arch bridges'. Previous masonry arch bridges only had a 'simple system' but no 'combined system'. The publication of the book "Filled Concrete Shell-Plate Arch Bridge" has filled the gaps in this type of bridge, and it is the first masonry arch bridge of the "combined system" in which the buildings on the arch and the main arch ring are jointly stressed. In the book "Filled Concrete Shell-Plate Arch Bridge", 10 bridge examples of this type of bridge are detailed structural checking calculations. At the same time, the industrial slag mixed material usually used in highway subgrade construction - stabilized soil is used for the first time. Bridge structure, and on the basis of a large number of experiments, put forward the strength calculation index of i...
