Tunnel lining structure health monitoring method and system based on digital twinning

Abstract

The invention discloses a tunnel lining structure health monitoring method and system based on digital twinning, and relates to the technical field of tunnel lining structure health monitoring. The system comprises a data acquisition system, a database system, a data processing system and a decision-making system; the data acquisition system comprises a surrounding rock displacement sensor, a surrounding rock pressure sensor, an underground water pressure sensor, a lining structure stress sensor, a secondary lining steel bar stress sensor and a lining structure deformation collector; the database system comprises a data transmission cloud platform, a digital twinning database and a theoretical threshold database; the data processing system comprises a data analysis platform; the decision-making system comprises an early warning module and an evaluation module. According to the method and system, health monitoring is conducted on stress and deformation data of a tunnel lining structure, the health state of the tunnel lining structure is mastered in real time through the digital twinning technology, the tunnel lining structure is prevented from being damaged by stress, the operation safety of the tunnel lining structure is guaranteed, and the stability and durability of the tunnel structure are improved.

Description

technical field [0001] The invention belongs to the technical field of tunnel lining structure health monitoring, and in particular relates to a digital twin-based tunnel lining structure health monitoring method and system thereof. Background technique [0002] Due to the particularity of the tunnel lining structure in the underground environment, it will be affected by various factors during the long-term operation process, such as topographic and geological conditions, hydrological conditions, climate conditions, surrounding building environment, etc., as well as the design, construction, and operation processes. Lead to different types of disease conditions in the long-term operation process. Once tunnel structural damage occurs, lining cracks will continue to expand under long-term loads, reducing the bearing capacity of the tunnel lining structure, eventually leading to the stability of the tunnel structure, and greatly increasing the risk of safe operation of the tunn...
