Abstract

The invention discloses a long tunnel multi-observation-station combined measurement combination resolving method and device and a storage medium. The method comprises the following steps that a first control point and a second control point are arranged at the two ends of a tunnel deformation area respectively; dividing the tunnel deformation area into a plurality of measurement sections according to a preset distance rule, and arranging total stations in the measurement sections; arranging a monitoring point in the measuring section; arranging a joint measurement point at the junction of the measurement sections; the total station acquires angle data and distance data of the monitoring points in the monitoring section; calculating according to the angle data and the distance data to obtain a three-dimensional coordinate of the monitoring point; and carrying out statistical analysis on the three-dimensional coordinates of the monitoring points to obtain the variable quantity of the three-dimensional coordinates of the monitoring points. The technical problem that long tunnel deformation monitoring is difficult in the prior art is solved, deformation monitoring of the long-distance tunnel is achieved by constructing the joint measurement elevation network and the plane network, and safety of adjacent buildings and railways is guaranteed.

Description

technical field [0001] The invention relates to the field of underground engineering measurement, in particular to a combined solution method, equipment and storage medium for joint measurement of long tunnels and multiple measurement stations. Background technique [0002] During the construction of the surrounding buildings of the subway tunnel, the excavation of the foundation pit may cause the deformation of the subway tunnel, thus causing hidden dangers to the safe operation of the subway. Therefore, it is necessary to carry out safety monitoring work on the nearby subway tunnels during the construction of surrounding buildings. [0003] In the prior art, a single total station is generally used to accurately measure the deformation area of ​​the tunnel; however, the viewing distance of a single total station is limited, and when the excavation scale of the foundation pit is large and the potentially affected tunnel is long, It is impossible to accurately measure the d...
