基于三维激光扫描的危岩体清除治理设计

Design of Rock Mass Removal Management Based on 3d Laser Scanning

摘要:

危岩体崩塌是地质灾害的常见形式，对人口密集区域和工程施工威胁很大，因此需要对其进行加固或者清除。此类地质灾害多分布在山区，由于地形复杂、植被茂密，传统的测量方法耗时、耗力且数据误差大。三维激光扫描技术具有快速和非接触的特点，它能辅助内业设计人员分析识别危岩体存在，为危岩体稳定性分析提供精确、多元化的基础数据，为设计方案工程量计算和投资预算提供精确数值。文中结合工程实例介绍了三维激光扫描的作业方法，以及辅助危岩体清除治理设计的全过程，为以后类似项目提供一定参考。

Abstract:

As a common form of geological disasters, the collapse of dangerous rock mass poses a great threat to densely populated areas and engineering construction, so it needs to be reinforced or removed. Such geological disasters are mostly distributed in mountainous areas. Due to complex topography and dense vegetation, traditional measurement methods are timeconsuming, laborconsuming and data error is large. 3 d laser scanning technology is fast and the characteristics of noncontact, it can assist designers in the industry analysis to identify dangerous rock mass exist, as the basis of the dangerous rock mass stability analysis to provide accurate, diversified data, as the design scheme of quantities and the budget of the investment to provide accurate numerical calculation. In this paper, the operation method of 3d laser scanning and the whole process of assisting the removal design of dangerous rock mass are introduced with an engineering example, which will provide some references for similar projects in the future.
