Abstract

The difficulty to optimize and control the large cavern group construction is how to construct the system description model and assure the control criterion. Aiming at the complexity and uncertainty of the geologic region, the large cavern group construction system intelligence analysis methods were studied, including 3D numerical simulation-intelligent evolution method, deformation time series prediction method and knowledge based control criteria. Integrating above methods, the IDSS was developed and used in the underground powerhouse construction control of Qingjiang Shuibuya hydroelectric project. The IDSS finished surrounding rocks stability appraisement, rock mechanical parameters back analysis, and anchor schemes multiple objects optimization, which got satisfactory results. Integrated intelligence method improves the analysis speed and validity, it is feasible in complex cavern construction real-time control
