Bridge temperature measuring method, device and equipment and readable storage medium

Abstract

The invention relates to the technical field of bridge safety monitoring, and provides a bridge temperature measurement method, device and equipment and a readable storage medium. The method comprises the following steps: determining a target time sequence corresponding to a to-be-measured bridge, wherein the target time sequence is used for representing daily meteorological data in an environment where the to-be-measured bridge is located; based on the target time sequence, determining the initial temperature of the to-be-measured bridge and the radiation temperature of the to-be-measured bridge; determining a first surface fluid temperature of the to-be-measured bridge according to a preset first condition; determining the fluid temperature of a second surface of the to-be-measured bridge according to a preset second condition, wherein the second surface is a surface opposite to the first surface; and determining the temperature of the to-be-measured bridge based on the initial temperature, the radiation temperature, the first surface fluid temperature and the second surface fluid temperature. And the daily meteorological data in the environment where the bridge is located and the internal temperature of the bridge structure can be combined to quickly calculate the temperature field distribution of different structures and different construction stages of the bridge.

Description

technical field [0001] The invention relates to the technical field of bridge safety monitoring, in particular to a bridge temperature measurement method, device, equipment and readable storage medium. Background technique [0002] In the construction process of high-speed railways, bridges are often used to replace roads. Some thorny problems are encountered in bridge design, construction, and traffic operation. Bridge temperature is a factor that cannot be ignored; bridge temperature changes with time as a random process. The spatial and temporal distribution rules directly affect the bridge design, construction and working status of the line. Among them, the temperature effect of high-speed railway bridge-track system caused by environmental factors such as seasonal alternation and solar radiation is the key to the study of bridge temperature. A large number of engineering examples show that the temperature stress caused by the temperature field of concrete bridges far e...

Problems solved by technology

The heat transfer mechanism and temperature change reasons of some long-span complex bridges are still unknown

For example, the steel box truss-ballastless track cable-stayed bridge of high-speed railway, compared with the traditional ballasted railway, this high-speed railway bridge presents a bridge form with a large span and complex system, and the corresponding bridge temperature monitoring system is more cumbersome. The requirements are also extremely strict; limited by the cost of the temperature monitoring system, it is impossible to monitor the temperature of the bridge in all aspects
