Abstract：With integrated applications of artificial intelligence，system science，rock mechanics and engineering geology，a new methodology has been proposed for evaluation and prediction in space-time for the safety of rock engineering under hazardous environment. It includes integrated back analysis of rock mechanical parameters，intelligent recognition of the mechanical models structure and its parameters，finite element analysis in parallel with dynamically updating the model and parameters of rock masses，evaluation and prediction in space-time for the safety of rock engineering under hazardous environment in parallel with dynamically updating the model and parameters of rock masses，zoning self-adaptive support design for the safety of rock engineering under hazardous environment，intelligent system for the integration of multiple information and tasks for the safety of rock engineering under hazardous environment. The proposed method has been successfully applied to risks evaluation and optimal design for slopes and cavern groups in Longtan，Shuibuya，Bachimen，Laxiwa projects，etc.. The results are satisfied.
