Based on the Delphi method of deep excavation safety risk analysis

Abstract

To prepare the construction and the construction of underground project risk assessment is necessary. The choice of evaluation theories the correctness of the evaluation result has an important influence. The paper briefly introduces the basic ideas of Delphi method. It focuses on the application of Delphi method for deep excavation engineering risk assessment procedure and standard. The analysis results show the Delphi method applied in underground engineering feasibility of risk analysis, scientific and reasonable.
