基于GIS与虚拟现实技术的三维地层可视化系统设计与实现

The design and realization of 3D geological modeling system based on GIS and VRML

本文在对比多种三维可视化建模方法的优劣后,提出了一种在VRML环境下结合GIS技术实现三维地层可视化的方法,并以某大桥为例,将理论的虚拟现实技术推广到实际应用中,克服了依靠传统钻孔柱状图来反映真实地层分布的弊端,大大提升了勘察结果表达的直观性,给工程勘察信息的整理发布提供了一个有效、科学的技术手段。

Based on the comparison of various 3D geological modeling methods, the authors of this paper proposes a way with the combination of VRML and GIS technology, and takes a highway bridge as an example for the theory in practical application. At the same time, in order to overcome the drawbacks of the traditional profile, the authors have designed a 3D geological modeling system which provides an efficient method and a scientific view for the information management of geotechnical investigation and surveying.
