Tunnel surrounding rock deformation monitoring method and monitoring system

Abstract

The invention discloses a tunnel surrounding rock deformation monitoring method and monitoring system. The system comprises an automatic data acquisition system, a wireless remote transmission system,a computer cloud, an engineering project management center, a warning device and a post-processing system; the automatic data acquisition system comprises a sensor, a data acquisition device and a short-range wireless transmission and receiving device; the computer cloud includes a base station, a remote wireless transportation device and a server; the engineering project management center includes a data analysis processing system, a management center, a report center, and other processing systems; the computer cloud and the engineering project management center share data with each other; and after receiving warning information, the warning device issues an early warning of a corresponding level, and determines whether to send preventive measure information to the post-processing systemaccording to the warning level. With the tunnel surrounding rock deformation monitoring method and monitoring system of the invention adopted, all-weather, real-time continuous monitoring and early warning of the surrounding rock of a tunnel can be realized, the lives of construction workers can be prevented from being exposed to dangers, damage to mechanical equipment can be reduced, and accidents caused by the large deformation of the surrounding rock can be prevented advance.

Description

technical field [0001] The invention relates to the technical field of tunnel surrounding rock monitoring, in particular to a tunnel surrounding rock deformation monitoring method and a monitoring system thereof. Background technique [0002] With the rapid development of national construction, the current highway and railway tunnels have some new features: large cross-section, long tunnel, complex geological conditions, and unfavorable ground conditions in front of the tunnel excavation face can easily cause tunnel collapse and water gushing. These factors not only bring great difficulties to tunnel construction technically, but also often cause personal casualties and delays in construction due to unexpected accidents, resulting in huge economic losses. [0003] The current methods and tools used for tunnel monitoring have become more and more limited with the increasing tunnel span or the increasing difficulty of monitoring, and the accuracy and error of monitoring are in...

Problems solved by technology

These factors not only bring great difficulties to tunnel construction technically, but also often cause personal casualties and delays in construction due to sudden accidents, resulting in huge economic losses. At the same time, they have also attracted the attention of national regulatory authorities

[0003] The current methods and tools used for tunnel monitoring have become more and more limited with the increasing tunnel span or the increasing difficulty of monitoring, and the accuracy and error of monitoring are increasingly unable to meet the requirements. Furthermore, the current The monitoring method also cannot carry out real-time monitoring, does not have the function of automatic alarm or early warning, and there are factors that affect

[0004] In addition, some conventional monitoring instruments and methods also have some fundamental defects: point measurement, less information; difficult to achieve distributed monitoring, often missing some important information for engineering safety; poor durability; vulnerable to strong Electromagnetic field interference affects measurement accuracy; it is not suitable for harsh environments such as flammable, explosive, high temperature, and lightning strike areas; it is inconvenient for long-distance telemetry and monitoring, etc.
