Abstract

The invention discloses a reinforcement method for a reinforced concrete box-type roadbed, and particularly relates to the technical field of constructional engineering. A transversely closed rectangular cavity structure is formed by a bottom plate, a vertical plate and a top plate through reserved steel bars and corresponding upper holes or lower holes; according to top plate midspan bending moment, double-rib pavement design judgment and corresponding reinforcement calculation synchronously, fixed end bending moment calculation and midspan bending moment calculation of a vertical plate are matched, and a base net counter-force design value is adaptively calculated by a bottom plate aiming at the overall upper load of the vertical plate and the top plate, so that reinforcement of the bottom plate is completed, and a cavity structure is integrally formed; the method has the advantages that the structure strength is good, the reinforcement strength is high in accuracy and reliability, the rectangular cavity structure constructed through the reinforcement method meets the bearing capacity requirement, the use function requirement and the construction requirement, and the method has the advantages of being economical, reasonable, good in integrity, high in construction efficiency and high in operability; and the engineering requirements on high-speed railway tracks in the new era are met.

Description

technical field

[0001] The present invention relates to the technical field of construction engineering, and more particularly, the present invention relates to a reinforcement method for a reinforced concrete box-type roadbed. Background technique

[0002] With the continuous development of high-speed railway projects in my country, the mileage of high-speed railways has increased rapidly. Due to the large difference in geological conditions in the areas where high-speed railways are laid, the traditional railway subgrade construction process cannot adapt to the differentiated geological conditions in different regions. , the overall strength is difficult to achieve the specified strength index, so a new type of roadbed is urgently needed to replace the traditional roadbed to meet the needs of the project. Aiming at the difficulty in laying the traditional roadbed or the strength of the traditional roadbed cannot meet the running requirements of high-speed trains due to engi...
