Concrete bridge dead load stress testing system and method and information data processing terminal

Abstract

The invention belongs to the technical field of bridge dead load stress testing, and discloses a concrete bridge dead load stress testing system and method and an information data processing terminal.The concrete bridge dead load stress test system comprises a bridge image acquisition module, a bearing acquisition module, a bridge prestress detection module, a main control module, a bridge modelconstruction module, a parameter import module, a simulation test module, an analysis module, a storage module and a display module. The real-time relationship between the tension strength (tension force) and the tension displacement is established through real-time measurement data by the bridge prestress detection module, the magnitude and uniformity of effective prestress are intelligently controlled, and the bridge prestress detection precision is improved; and moreover, the analysis module is used for obtaining the stress cycle data of a to-be-analyzed bridge through adoption of a data simulation method based on the actually measured traffic flow data of the to-be-analyzed bridge, the theory is scientific, the analysis result is scientific and reliable, the applicability is high, andimportant engineering significance is achieved.

Description

technical field [0001] The invention belongs to the technical field of bridge dead-load stress testing, and in particular relates to a concrete bridge dead-load stress system and method, and an information data processing terminal. Background technique [0002] At present, the closest existing technology: prestressed concrete bridge is also called prestressed reinforced concrete bridge, and the bridge span structure adopts the bridge built by prestressed concrete. This kind of bridge can make the concrete pre-compressed before loading by using the reaction force of steel bar or steel wire (cable) pretension. There is no tensile stress in the operation stage (called fully prestressed concrete), or there is tensile stress without cracks or cracks are controlled within the allowable width (called partly prestressed concrete). However, the prestress detection error of existing concrete bridges is large; at the same time, the bridge load cannot be accurately analyzed. [0003] ...
