摘要
The prediction of rock mass behaviour is an important task in many engineering projects, as the behaviour of rock masses can be controlled by the presence of discontinuities. Being able to map the structure of a rock mass is crucial to understanding its potential behaviour. This understanding can positively impact on the safety and efficiency of an engineering project. In this research, rock masses were modelled and analysed using linear mathematical transformations and isometric perspective methods to achieve meaningful three-dimensional results. The rock mass fracture representation is based on explicit modelling of rock faces. The developed model can improve safety and productivity through its application in the determination and analysis of rock mass structure for geological and geotechnical assessment. Based on the methods explained here, a software system was developed for analysing the geometric characteristics of discontinuities in a rock mass. In this model, discontinuities in a rock mass can be visualised both individually and in combination, and cross-sections can be generated at any desired location. In addition, intersection lines between discontinuities can be generated as dip direction vectors. The natural structure attained by using this developed model agrees well with field measurements.
