Bridge load test quick detection system

Abstract

The invention belongs to the technical field of bridge detection, and discloses a bridge load test quick detection system. The system comprises a wireless strain collection system, a wireless deflection collection system, a wireless load vehicle locating system, a base station receiving system and a bridge bearing capacity evaluation system. According to the bridge load test quick detection system disclosed by the invention, the test cost is reduced; only one load vehicle slowly runs on a planned lane; the system records response data of all detection points in real time and associates the response data with moving positions of the load vehicle in real time; influence lines of all the detection points are obtained through actually tested data; loads with different efficiencies are applied based on the influence lines to estimate the bridge bearing capacity.

Description

technical field [0001] The invention belongs to the technical field of bridge detection. Background technique [0002] With the rapid development of society and economy, the traffic volume continues to increase, and the number of loads on the bridges put into use becomes larger. Due to the degradation of the material's own performance and the influence of the environment for a long time, different degrees of damage occur. Therefore, the bridge Carry out regular load testing, make a scientific assessment, fully understand whether the actual working conditions of the bridge still meet the design requirements, and ensure the safe use and operation of the bridge. The existing load test method is mainly: rent multiple load vehicles to load at a fixed position of the bridge, measure the response data by collecting equipment, and evaluate the bearing capacity. Due to the complex structure of the bridge, the large span and many interference factors on site, the difficulty of distin...

AI Technical Summary

Problems solved by technology

Due to the complex structure of the bridge and the large span, there are many interference factors on site, and the difficulty of distinguishing a large number of wiring and cables will inevitably bring many disadvantages to the bridge inspection, and the cost is high, requiring a lot of manpower

Considering various factors such as cost, bridge load tests are mostly carried out once a year or every few years, resulting in a small amount of information on the measuring point data and not being continuous, which affects the accuracy and real-time performance of bridge detection
