In recent years,there are growing demands of representing rock mechanics and rock engineering in a digital format that can be easily managed,manipulated,analyzed and shared.The objective of this paper is to give a comprehensive review of the status quo and future trends of digitization in rock mechanics and rock engineering.Research topics essential to the process of digitization are firstly discussed,including data acquisition,data standardization,geological modeling,visualization and digital-numerical integration.New techniques that will play an important role in digitization process but require further improvement are then briefly proposed.Finally,achievements of present methods and techniques for digitization in substantial rock mechanics and rock engineering are presented.
