Research Progress of Three-Dimensional Engineering Geological Evaluation Modeling

With the rapid development of China’s economic construction and the increasing scale of the project, more and more complex engineering geological problems have put forward higher requirements for engineering geological researchers. As the core link of engineering geological research, engineering geological evaluation provides a key scientific basis for solving engineering geological problems. The engineering geological evaluation model is a good tool and means to support the realization of the evaluation method. Therefore, it is urgent to study three-dimensional engineering geological evaluation modeling systematically. In view of the current situation that the construction methods of the three-dimensional engineering geological evaluation model in the field of infrastructure construction at home and abroad are not uniform, this paper briefly summarizes the research progress of the three-dimensional engineering geological evaluation model. It focuses on three-dimensional geological modeling and the three-dimensional engineering geological space evaluation index system. This study discusses the main methods for comprehensive engineering geological evaluation and the construction of a three-dimensional geological model. At the same time, in response to the low accuracy of current three-dimensional engineering geological evaluation models and their insufficient integration with numerical simulations, this paper proposes improvement suggestions and outlines the development trends of such models. The purpose of this paper is to deepen the engineering geological evaluation work, promote its sustainable development, and lay the foundation for the study of a three-dimensional engineering geological evaluation model so as to cope with more complex engineering geological challenges in the future.
