Embodiment Construction

[0033] The invention provides a brand-new bridge intelligent monitoring method, which realizes the analysis and prediction and real-time monitoring of the mechanical response of the bridge structure, and simultaneously performs real-time monitoring of vehicle loads, traffic flow analysis, prediction and control. By evaluating the safety of the bridge structure and controlling the traffic flow, it is possible to prevent damage or damage to the bridge structure caused by overloading of vehicles or excessive concentration of traffic, so that the bridge is in the best operating state, reducing the maintenance cost of the bridge and extending the service life of the bridge. In addition, with this monitoring method, the bridge can be reasonably opened to traffic under severe conditions such as strong winds and earthquakes.

[0034] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in...

Abstract

The invention discloses an intelligent bridge monitoring method based on traffic flow control, which is characterized in that: the traffic flow control is introduced into bridge monitoring, a method combining monitoring and forecasting analysis of vehicle load flow, forecasting analysis of bridge structural mechanics response, real-time monitoring of bridge structural safety condition and active control of the traffic flow is adopted, and a reasonable vehicle load model is established through monitoring and forecasting analysis of the vehicle load to be on a bridge so as to perform the forecasting analysis of the bridge structural mechanics response and pre-evaluation of safety condition, and control the traffic flow according to a pre-evaluation result; the bridge safety condition is comprehensively evaluated through bridge theoretical calculation and the analysis of a real-time monitoring result, and the traffic flow is controlled according to an evaluation result; and the active control of the traffic control effectively avoids the damage caused by extra bridge load, prolongs the service life of the bridge, and can reasonably control the traffic flow in an allowed range of ensuring bridge operation safety in special conditions such as strong wind, earthquake and the like.

Description

technical field [0001] The invention belongs to the technical field of civil engineering bridge monitoring, and discloses a bridge intelligent monitoring method based on traffic flow control. Background technique [0002] At present, the bridge monitoring method is to monitor the mechanical response of the bridge structure after the external load is applied, evaluate the safety state of the bridge according to the bridge structure response and perform simple traffic control. The disadvantages of this method are as follows: [0003] (1) Bridge monitoring in the prior art is to measure the bridge structural response (stress, deflection, etc.) Concentrated damage to the bridge structure cannot be prevented; for example, there was an accident in which overweight vehicles damaged 5 bridges overnight on a trunk road in Hebei Province, and there are huge hidden dangers in the safety of bridges in the operation stage. [0004] (2) The bridge monitoring in the prior art is too simpl...
