Skew bridge load test loading vehicle positioning system and method

Abstract

The invention discloses a skew bridge load test loading vehicle positioning system and method. The system comprises a meter ruler, a skew bridge slope horizontal angle measurer, a computer and a vehicle arranging control device. The vehicle arranging control device comprises a right front vertical marker post, a right rear vertical marker post, a left rear vertical marker post, a left front vertical marker post, a front induction rope, a rear induction rope, a right laser transmitter, a right laser receiver, a left laser transmitter, a left laser receiver and a vehicle arranging controller, and the front induction rope and the rear induction rope are respectively composed of a hemp rope, a reflecting rubber belt and a pressure sensor. The method comprises the steps of (1) measuring and setting parameters, (2) calculating arranging position coordinates of a loading vehicle, (3) arranging the vehicle arranging control device according to the arranging position coordinates of the loading vehicle, and (4) positioning the loading vehicle through the vehicle arranging control device. According to the system and method, the accurate skew bridge load test and the rapid vehicle arranging are achieved, and the test efficiency and reliability of experimental data of the skew bridge load test are improved.

Description

technical field [0001] The invention belongs to the technical field of inclined bridge load tests, and in particular relates to a loading vehicle positioning system and method for inclined bridge load tests. Background technique [0002] With the continuous development of the national economy and the continuous enhancement of comprehensive national strength, the comprehensive and rapid development of my country's high-grade highways has been driven. In order to obey the plane layout of the route and improve the use and safety performance of the bridge, the proportion of the inclined bridge in the structure is increasing. Therefore, the design, detection and evaluation of the inclined bridge have important practical value. [0003] The load test of the inclined bridge is a scientific experimental work of direct loading test on the inclined bridge structure, which is used to understand the actual working state of the inclined bridge, so as to judge the safe bearing capacity of...

AI Technical Summary

Problems solved by technology

However, for different bridge types, especially for inclined bridges, due to the limitation of inclined bridge slope, bridge deck width and other factors, there is a deviation between the actual vehicle loading position and the theoretical vehicle loading position in the load test, which affects the judgment of the safety of the bridge structure. Carrying capacity and assessment results of the operational quality of bridges
