Imperfections of measurement frequency,data processing and danger prediction in tunnel monitoring is analyzed,and methods are proposed for improvement.The results show that considering excavation time, excavation conditions and measurement data,adoption of standard for measurement frequency determination and dynamic measurement frequency calculation is more reasonable.Hyperbolic function regression method applies to plastic rock,while exponential regression applies to brittle rock in data processing.Standard of danger prediction involves multiple factors,which should be comprehensively analyzed and finally reached by experience.
