Abstract
Aiming at the dynamic feedback and control of the surrounding rock stabihty for underground cavern group,a 4-D model is introduced herein to establish the dynamic safety information model of large underground cavern group,and then the project information,geological information,safety monitoring information,numerical simulation information,etc.are coupled into the study of the dynamic feedback and control of the surrounding rock stability for underground cavern by taking "verification of the result from the prophase inverse and feedback analysis—dynamic inverse analysis of instant parameters—prediction of the dynamic behavior of the cavern surrounding rock during the next phase of excavation" as the cyclic process.The effective mapping relationship between the 3-D visualization synthesized engineering model and the dynamic information during construction is established through coupling visualization technique,detection analysis theory,parametric inversion theory,numerical simulation technique and computer technique as well as simulating the dynamic construction process with the programming technique of C#.NET at the same time,so as to realize the rapid,accurate and real-time reflection of the status of the safety of underground cavern group under the construction environment,and thus provides a reference for the design optimization during construction.关键词
