考虑不确定性的隧道工程稳定性分析与可靠性优化设计
Stability analysis and reliability optimization design of tunnel engineering considering uncertainty
摘要
Abstract
Uncertainty is a critical property of rock engineering and is important to stability analysis,design and safety construction of rock engineering.But the traditional determinate methods do not consider the uncertainty of rock engineering.In this paper,a novel approach,which considers the uncertainty through combining reliability theory,experimental design,numerical simulation and response surface,was proposed and applied to tunnel engineering.The uncertainty analysis model of tunnel was presented in brief.An un-certainty—based design method was proposed based on the above model.The proposed method was verified by a numerical example.The results show that the proposed method provides obvious instructions for de-sign,stability analysis and risk analysis in tunnel engineering,and is an effective and feasible approach for tunnel uncertainty analysis.关键词
