基于激光點(diǎn)云的隧道斷面連續(xù)提取與形變分析方法
[Abstract]:The monitoring and measurement of subway construction and operation stage can effectively ensure the stability of tunnel structure and the safety of the surrounding environment. Although the existing deformation monitoring methods, such as convergence meter and total station, can obtain high precision observation data, the monitoring points obtained are too sparse to reflect the deformation characteristics of the tunnel in an all-round way. In this paper, three-dimensional laser scanning technology is applied to deformation monitoring of subway tunnel, and a continuous extraction and deformation analysis method of tunnel section based on laser point cloud is proposed, and the deformation analysis of the two extracted sections is carried out. the experimental results show that this method can more intuitively express the overall deformation of tunnel, and the research results can be used for reference for dynamic monitoring of tunnel deformation.
