多种测绘方法在张家界天门洞崩塌地质灾害中的应用研究

Research on the Application of Various Surveying and Mapping Methods in the Geological Hazard of Tianmen Cave Collapse in Zhangjiajie

以张家界天门洞国家5A级景点的崩塌地质灾害为研究案例,利用不同测量技术快速获取研究区多角度影像数据,通过Context Capture软件构建不同格式实景三维模型,同时运用CloudCompare、Trimble realworks viewer等软件,对灾区地质灾害隐患风险进行识别分析和信息提取,进而完成研究区地质灾害调查与评估和地质灾害勘查任务。多种测绘方法的应用研究为解决高位和特高危岩体的分析识别工作提供了一种新思路。

This article takes the geological disaster of the collapse of the Tianmen Cave,a National 5A scenic spot,in Zhangjiajie City as a research case,uses different measurement techniques to quickly obtain the multi-angle im-age data of the research area,and constructs the real 3D models of different formats by Context Capture software.At the same time,it uses software such as CloudCompare and Trimble realworks viewer to identify and analyze the hidden risks of geological disasters in the disaster area and extract information,so as to complete the tasks of geologi-cal hazard investigation and assessment,as well as geological hazard exploration in the research area.The application research of various surveying and mapping methods provides a new idea for solving the analysis and identification of high-level and extra-high dangerous rock masses.
