Topology and its various benefits are well understood within the context of 2D Geographical
Information Systems. However, requirements in three‐dimensional (3D) applications have …

Deformations and stress distributions in tunnel intersection areas are more complicated than
those in common tunnels. The literature on deformations and stress distributions in tunnel …

One of the main causes of problems during the construction of tunnels with tunnel boring
machines (TBMs) is a lack of characterization of the soil. Both geological and …

In this study, an extension called Tunneling Analyst (TA) has been developed in ArcScene
3D GIS software, part of the ArcGIS software package. It dramatically extends the …

This paper reports a geological modelling procedure suitable for the reconstruction of three-
dimensional models and for applications in preliminary tunnelling studies. The geological …

The main goal of 3D modeling studies in the mining sector is to address the complex
geological, mineralogical, and structural factors in subsurface environments and detect the …

Spatial modelling of geotechnical parameters can help engineers tackle the inherent
uncertainty related to the subsurface. In the paper, the 3D spatial modelling is used in order …

Modern cities have been trying to meet their needs for space by using not only surface
structures but also by considering subsurface space use. It is also anticipated that without …

针对前人研究的不足, 提出了一种井巷工程无缝快速开挖新方法. 该方法地质模型采用广义三
棱柱(GTP) 构建, 并借助“最小顶点标识法” 将地质模型转换为三角形集合组成的边界表示模型; …

Based on the solid modeling, transformation operation and Boolean operation techniques
widely available in computer-aided design and drafting system, first, this paper proposed a …
