Description

Non-contact measurement system and method for non-uniform displacement of roadway/tunnel surface

Technical field

The invention relates to a non-contact measurement system and method for roadway/tunnel surface displacement, in particular to a roadway surrounding rock deformation measurement system suitable for high-precision measurement of non-uniform deformation under irregular roadway surrounding rock conditions.

Background technique

The surface deformation of the tunnel/tunnel is the most basic engineering monitoring parameter, which mainly includes the distance of the tunnel/tunnel roof, floor and side walls. Based on the monitoring results, the displacement velocity of the tunnel/tunnel surface and the convergence rate of the tunnel/tunnel section can be calculated, and Establish and draw the relationship curve between displacement amount, displacement velocity, tunnel/tunnel excavation position and time, and then analyze the deformation law of tunnel/tunnel surrounding rock, surrounding rock stability and tunnel/tunnel support effect. At present, the monitoring method of surface deformation of roadway/tunnel generally adopts the cross measurement method, that is, drilling holes in the vertical direction of the top of the roadway/tunnel, the middle part of the floor and the two sides of the horizontal direction, and installing wooden piles, short anchors, measuring nails and other measurement base points. Personnel perform manual measurements and recording.

Considering that the roadway/tunnel in the project is affected by ground stress, lithology, rheology, or blasting impact, the initial cross-sectional shape and unevenness usually vary greatly, and the surface of the surrounding rock is non-uniformly deformed. The traditional method is limited by the influence of the location of the measuring points and is mainly suitable for uniform deformation of the surrounding rock surface of regular tunnels; manual recording is limited to a certain section of the tunnel and cannot achieve overall measurement; it is easy for workers to record data in a timely manner and with low accuracy. Leading to inaccurate data analysis, etc. The above problems have brought many difficulties to the measurement of roadway surface deformation. It can be seen that the existing technology needs further improvement and improvement.

Optical measurement tools have simple structures, high measurement accuracy, and strong applicability in harsh environments. The use of pulse measurement devices such as laser rangefinders can realize real-time measurement of the deformation of surrounding rock in tunnels, and accurately measure long-distance tunnels in one go. The amount of deformation in the direction is used to determine the shape of the deformed surrounding rock.

After searching and querying, relevant research reports on the existing technology include:

"Laser Measurement Device and Method for Surface Deformation of Roadway Surrounding Rock" (Announcement No.: CN103510985A) uses computer software units to process roadway surface deformation data, draw roadway graphics, analyze the surrounding rock deformation at each measurement point of the roadway, and predict the danger of the roadway. Suitable for accurate measurement of tunnel surrounding rock deformation. However, this device is mainly suitable for measuring the uniform deformation of the surrounding rock surface of a relatively regular tunnel, and it is more difficult to complete the measurement of the deformation of the entire tunnel section. "A dynamic measurement device for tunnel surrounding rock deformation" (Announcement No.: CN201680823U) uses multiple laser ranging sensors spaced on the sides and top of the tunnel to achieve automatic, real-time, multi-section and continuous long-term measurement of tunnel deformation. It is suitable for Real-time measurement, data storage, image display and data communication of tunnel surrounding rock deformation. However, the selected laser rangefinder is not equipped with a rotating device and cannot measure the entire tunnel section. A large number of laser rangefinders are required to complete a measurement. "A device and method for monitoring the surface deformation of the entire tunnel and the entire process" (Announcement No.: CN106401651A) uses anchor cables to arrange the measuring stations, and uses the threaded casing at the end of the anchor cables to connect the support frame and the rotating laser measurement device. Through the rotating laser measurement The device realizes digital imaging of the entire tunnel, the entire process, and the entire section. The installation and line layout of this device are relatively cumbersome, the measurement and sampling intervals are highly random, and the anchor cable as the installation carrier is easily disturbed by the external environment.

Therefore, how to break through the above-mentioned problems existing in the existing laser measuring device for surface deformation of tunnel surrounding rock, that is, on the basis of accurately obtaining the deformation amount of the tunnel section in all directions, automatically adjusting the spatial distance of measurement sampling, and realizing the non-uniformity of the surface of irregular tunnel surrounding rock. Functions such as real-time monitoring of deformation, while reducing the impact of the external environment on the measurement device, reducing measurement costs, etc., are of extremely important research and engineering significance for rock mass engineering support and construction safety.
