摘要
基坑工程开挖过程中的监测是工程安全的重要保障,为了提高基坑监测的全面性和技术水平,本文通过工程实例介绍了三维激光扫描技术在房屋建筑基坑变形监测中的理论及应用方法,采用三维激光扫描仪获取点云数据并建立了三维偏差模型,与传统的测斜方法等进行了比对和精度分析,提出了提高精度和稳定性的具体改进措施。
Excavation moniforing process is an important guarantee for the safety of the project, in order to improve the technical level of comprehensive and deep foundation pit, this article introduced 3D laser scanning technology by engineering example of ibundation pit det0rmation monitonng. Usrog 3D laser scanner to collect the point cloud data and established the 3D deviation model. Compared with the traditional survey methods, this article indicated the 3D laser scanning technology achieved the same accuracy. In the end, the specific measures were proposed to improve the accuracy and stability.
