Abstract:

At present, it is difficult to record monitoring data when sluice are opened for flood discharge, especially in the case of dam deformation, the safety will be affected. Therefore, in order to understand the stability state of dam safety, a deformation monitoring system for reservoir dams based on 3D laser scanning is proposed. The working principle and equipment functions of the deformation monitoring system are introduced. The point-to-surface deformation comparison analysis mode is used to monitor dam deformation, and the source program is developed to realize the processing, comparative analysis and modeling of the integrated monitoring point cloud data. The intelligent machine system is applied to the actual monitoring of dam deformation. The results show that the system meets the design requirements in terms of stability, reliability, real-time and accuracy, resulting in higher data integrity rate.

摘要:

当前我国水库大坝很难在水库开闸泄洪时记录监测数据,尤其是在水库大坝变形的情况下,安全会受到 影响。因此,为了解大坝工作安全的稳定性,提出了基于三维激光扫描的水库大坝变形监测系统,介绍了水库大 坝变形监测系统工作原理和设备功能。运用点到面变形量对比分析模式监测大坝变形量,并进行源程序开发,实 现一体化监测点云数据的加工、对比分析及建模处理。将智能机系统应用到大坝变形实际监测中,结果表明:该 系统在稳定性、可靠性、实时性和准确性等方面都满足设计要求,数据完整率更高。
