A monitoring system for safe operation of tunnels in cold regions

Abstract

The invention discloses a monitoring system for safe operation of tunnels in cold regions, including a data collection module, a data analysis module, a cloud storage module, a collection and analysis module, a data call module, a data encryption module, a data transmission module, a supervision module, and a data collection module The data information of each stage of the tunnel in the cold area, and the collected data information is sent to the cloud storage module. The cloud storage module classifies and stores different data information, and uses the analysis module to obtain the corresponding vehicle information and predicted vehicle information according to the environmental information. The data The analysis module analyzes the influence of vehicles on the temperature field, seepage field, and stress field of tunnels in cold regions based on vehicle information, calculates the frost heave rate of the soil, and then judges the quality of tunnels in cold regions. The supervision module can report to the tunnel supervision department in cold regions The alarm signal is issued, which provides a more accurate theoretical basis for the quality monitoring of tunnels in cold regions, and plays a role in preventing safety and quality problems of tunnels in cold regions.

Description

technical field [0001] The invention relates to the technical field of tunnels in cold regions, in particular to a monitoring system for safe operation of tunnels in cold regions. Background technique [0002] With the continuous development of our country's economy, the transportation is more and more developed. In many remote and cold areas of our country, due to the influence of the harsh environment, the tunnels are affected by the frost damage. The frost heaving force of the seepage water is the main factor of the tunnel frost damage in the cold area. , in order to overcome the freezing damage and erosion damage of concrete caused by the frost heaving force of water, there have been many researches on tunnels in cold regions in the prior art, for example, when the water frost heaves, the Galerkin method, trigonometric function, The research on the temperature field, seepage field and stress field of the tunnel, such as the fluid thermal coupling model, and the calculati...

[0002] With the continuous development of our country's economy, the transportation is more and more developed. In many remote and cold areas of our country, due to the influence of the harsh environment, the tunnels are affected by the frost damage. The frost heaving force of the seepage water is the main factor of the tunnel frost damage in the cold area. , in order to overcome the freezing damage and erosion damage of concrete caused by the frost heaving force of water, there have been many researches on tunnels in cold regions in the prior art, for example, when the water frost heaves, the Galerkin method, trigonometric function, The research on the temperature field, seepage field and stress field of the tunnel, such as the fluid thermal coupling model, and the calculation of the mathematical coupling model between different fields provide a theoretical basis for the design, construction and safe maintenance of tunnels in cold regions, but these calculations do not consider The impact of vehicles on the tunnel during the use of the tunnel, the vehicles passing through the tunnel will also affect the change of the temperature field of the tunnel, and the traffic volume of the tunnel is affected by the environment and traffic policies, which reduces the safety monitoring of tunnels in cold regions. Accuracy, increasing the manpower and financial resources spent during the maintenance of tunnels in cold regions
