Vertical rod type bridge flexiblity monitor system

Abstract

A monitoring system of deflection on bridge in vertical pole type comprises computer and mechanism set at monitored point. It is featured as connecting partial structure in mechanism set at monitored point to computer through wire.

Description

Technical field [0001] The invention relates to a system in the field of detection technology, in particular to a vertical rod bridge deflection monitoring system. Background technique [0002] The deflection of a bridge refers to the longitudinal displacement of the centroid at a certain cross section of the bridge in the direction perpendicular to the axis. Deflection is one of the important parameters for evaluating the safety of a bridge. It is closely related to the bearing capacity of the bridge and its ability to withstand destructive loads such as earthquakes. Excessive deflection will directly affect the speed and comfort of the bridge deck. Therefore, the monitoring of deflection is an important part of bridge health monitoring. [0003] The main functions required to monitor bridge deflection are as follows: (1) Monitor the deflection value occurring at a certain cross section of the bridge, and obtain the law of deflection distribution along the transverse direction o...
