Dynamic three-dimensional tunnel section deformation detection and analysis system, method and device

Abstract

The invention discloses a dynamic three-dimensional tunnel section deformation detection and analysis system, method and device. The method comprises the steps that a scanner is controlled to acquiretunnel section information and rail section information to acquire a point cloud data set; an inclinometer is controlled to acquire two-dimensional altitude data of a detection device; a total stationis controlled to acquire trajectory data of the detection device; the two-dimensional altitude data and the trajectory data are subjected to data synchronization integration on the basis of a synchronization signal to generate positioning information; a tunnel three-dimensional space information data set is generated according to the point cloud data set and the positioning information, and thendeformation analysis is conducted on a tunnel; and whether or not a boundary invasion phenomenon is generated is determined according to the point cloud data set and a preset boundary contour. According to the method, the three-dimensional space information data set can be quickly acquired in a short maintenance period to conduct deformation analysis and boundary invasion analysis on the tunnel, and the data acquisition efficiency is improved; and the data acquisition precision can be improved through joint movement of the scanner and a vehicle-borne platform, and then accurate evaluation on the safety state of the tunnel is achieved.

Description

technical field

[0001] The invention relates to the technical field of tunnel detection, in particular to a dynamic three-dimensional tunnel section deformation detection and analysis system, method and device. Background technique

[0002] With the development of the urban economy and the improvement of people's living standards, the scale of the city continues to expand. The urban spatial structure also generally develops from a single center to a multi-center along with the expansion of the city scale and the acceleration of the urbanization process. The traffic demand between the central urban area and the outer urban areas also increases rapidly. Based on this, it is particularly important to provide people with fast and convenient urban rail transit.

[0003] To solve this problem, one of the main measures is to develop efficient and convenient underground rail public transportation and establish an underground public transportation network. As the main carrier for ...
