Embodiment Construction

[0053]The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0054] The present invention provides a bridge deflection testing method based on rotation angle, which converts the change of the rotation angle of the bridge section into the change of the bridge deflection, that is, inclinometers are arranged on five sections of the bridge to measure the section rotation angle, and the (electrical) signal of the inclination change passes through the signal cable It is sent to the acquisition system in time, and the mathematical relationship formula between the deflection and the rotation angle of the bridge is calculated by using the inclination value of the section, and then the deflection at any position is calculated. The invention is easy to operate, has accurate test data, high measurement efficiency, stable and reliable performance, is not affected by c...

Abstract

The invention discloses a bridge deflection test method based on inclinometers. The bridge deflection test method comprises the following steps: an inclination measurement step for measuring the cross section corners of a bridge by setting the inclinometers at a plurality of cross section positions of the bridge so as to obtain the corner values of the inclinometers; a deflection test step for obtaining the combination coefficient of an n-order vibration type based on the difference of corner values collected by each inclinometer at the same moment and the initial corner value of each inclinometer and calculating to obtain bridge deflection based on the combination coefficient. The invention also discloses a bridge deflection test system based on the inclinometers.

Description

technical field [0001] The invention relates to a bridge deflection testing method, which is suitable for deflection testing at any position of any bridge span length, belongs to the technical field of bridge detection, and in particular relates to a high-precision and high-efficiency bridge deflection in the bridge detection process testing method. Background technique [0002] In the bridge inspection test, the deflection of the bridge needs to be measured, and the accuracy of the deflection measurement data is directly related to the assessment of the state of the bridge. At the same time, the timeliness of the bridge inspection is required to be high. Therefore, in the process of bridge inspection, a high-precision and high-efficiency bridge deflection test system is very important. In the prior art, the following methods are generally used for on-site testing of bridge deflection: 1. Using optical measuring instruments such as a level to measure bridge deflection. Alth...
