Abstract

The invention belongs to the technical field of engineering measurement, and particularly relates to a tunnel long-side wire cut-through measurement method. The tunnel long-side wire penetration measurement method comprises the following steps: testing the farthest effective distance in a tunnel; designing a wire side length and setting a plurality of wire points; respectively erecting a total station and a beacon, and debugging the beacon to the optimal observation brightness; connecting the electronic handbook with the total station, and setting a horizontal angle observation tolerance index; manually sighting the beacon to observe and record the horizontal angle, and automatically checking the precision in real time by an electronic handbook; dismounting the beacon and replacing the prism, and manually sighting the prism to observe the distance and record; and moving to the next position until all traverse points are observed. According to the invention, the length of the lead observation side in the tunnel can be increased, the number of lead stations can be reduced, the observation target under the side length of 1500m of the lead in the tunnel is clear and stable, the transverse through measurement precision of the tunnel is obviously improved, the economic benefit is higher, the practicability is higher, and the development and engineering application of precise engineering measurement of the ultra-long tunnel are promoted.

Description

technical field [0001] The invention belongs to the technical field of engineering measurement, and in particular relates to a method for measuring the penetration of conductors at the long side of a tunnel. Background technique [0002] In the construction of tunnel engineering, tunnel penetration must contain penetration error. The penetration error of tunnel engineering includes three directions: horizontal, vertical and vertical. Starting from the current measurement technology, performance of instruments and equipment, and engineering requirements, the horizontal penetration error is affected by the hole It is obviously the most difficult to meet the tunnel construction requirements due to internal measurement conditions. According to the measurement error propagation law, the lateral penetration error is mainly caused by the measurement factors of the wire in the tunnel; with the extension of the tunnel distance and the increase of the number of wire stations, the erro...
