Method for carrying out bridge engineering quality acceptance by utilizing three-dimensional laser scanning technology

Abstract

The invention discloses a method for carrying out bridge engineering quality acceptance by using a three-dimensional laser scanning technology, and the method is characterized in that the method comprises the following steps: S1, optimizing the distance between observation stations, the incident angle and the scanning resolution; scanning parameters; S2, point cloud data preprocessing, wherein point cloud data preprocessing mainly comprises point cloud data registration, point cloud data denoising and point cloud data compression; S3, verifying the point cloud model, measuring the actual bridge size by using a total station, comparing the actual bridge size with the size of the point cloud three-dimensional bridge model, and observing whether the point cloud model can represent the actual bridge current situation or not; and S4, applying the point cloud model to the overall configuration deviation of the bridge, and further determining the evaluation of the bridge engineering quality. The method provides reference for improvement and progress of construction quality control of large bridges, and provides help for popularization and application of three-dimensional laser scanning in the field of civil engineering. In the near future, more and more application of three-dimensional laser scanning in civil engineering quality control is believed, so that the level of construction quality management is improved.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a method for checking and accepting bridge engineering quality by using three-dimensional laser scanning technology. Background technique [0002] At present, in the quality management of bridges in our country, there is a lack of effective monitoring of visualization, less application of information and digital technology, lack of effective supervision of materials and materials, poor information exchange, and low effective utilization of information. Therefore, it is necessary to rely on advanced Construction monitoring technology and information management methods are used to realize the effective management of bridge construction quality. Although there is a quality control management agency in construction, there are still some outstanding problems in bridge quality management: [0003] 1) Weak awareness of bridge quality management. Managers' weak a...

Problems solved by technology

[0004] 2) There are quality management problems in the construction stage

The quality management of the construction stage lacks comprehensive quality control, such as relatively backward technical equipment, non-adoption of new technologies, and poor material supervision, etc., which reduce the quality of the bridge

[0005] 3) There are illegal construction phenomena

However, the current detection methods are difficult to measure the overall configuration, which is crucial to the safety of bridges with complex structures.
