摘要
研究目的:在滑坡研究中,会涉及大量与三维空间及位置有关的信息,如地质信息、位置信息、滑坡形态等,一般情况下,这些信息都以报表和二维图形的形式出现,由于这些信息无法给人以直观印象,因此不仅使用过程中很难对其予以充分利用,在需要综合多种信息时会显得更加难以把握,而在三维空间进行虚拟工程设计,布置和施工等进而分析其效果更是不可能之事,本文通过应用Open GL软件成功开发出滑坡三维可视化软件,将软件应用于滑坡模型的建立、滑坡数据管理、稳定性计算、三维动态模拟,解决滑坡预测预报及动态仿真模拟问题。研究结论:(1)利用Open GL进行二次开发,可成功用于滑坡的稳定性计算,还能根据计算结果实现滑坡滑动过程的动态模拟,其过程简单、易行、实用、科学。(2)将Open GL应用于滑坡,可对滑坡勘察设计、演示汇报及大学教学模拟提供很大帮助,可大大提高工作效率及工作水平。(3)本研究成功建立了滑坡空间形态的三维地面模型及三维滑坡断面模型,实现了地形图、断面图、钻孔资料绘制、保存、输出和滑动面连接等功能,为稳定性评价和工程设计提供了快捷手段。(4)通过工程实例的试算表明,在条件一致的情况下,计算结果与勘察报告结果是一致的。(5)该研究成果可应用滑坡三维可视化动态模拟及稳定性计算。
Research purposes： In the course of landslide research, a lot of the information related to the three dimensional space and position are involved, such as the geological information, location information and landslide shape etc. In general, all these informations appear in the form of statements and 2D graphics, they can not give a person an intuitive impression. In this way, it is difficult to make full use of these informations and grasp these informations when it is necessary to integrate the informations, and it is impossible to analyze the their applicable effects for the arrangement and eonstruetion when making the virtual engineering design with the 3D space. In this paper, the 3D visualization software for the landslide is successfully developed with the Open GL software for building the landslide model, managing the landslide data, calculating the stability and conducting the 3D dynamic simulation to solve the problems of the landslide prediction and dynamic simulation. Research conclusions：（ 1 ） Using the Open GL to make the secondary development can successfully calculate the landslide stability and realize the dynamic simulation of the sliding process of the landslide according to the calculation results, with the simple, easy, practical and scientific process. （2） If the Open GL is used for landslide, it can provide the grat help for the landslide survey and design, the demonstration and the teaching simulation, and it can greatly improve the working efficiency and working level. （3） By using the 3D terrain model of the landslide spatial form and the 3D landslide section model, the functions of the mapping, storing and outputting of the topographic maps, sectional drawing and drilling data and connecting sliding surface etc can be realized, and it provides the rapid means for the stability evaluation and engineering design. （4） The trial calculation of engineering practice show in the same condition, the calculation result is in line with the result of the survey report. （5） This study result is available for the dynamic 3 D visualization simulation and stability calculation of landslide.
