基于灰色理论的隧道围岩收敛预测

摘要

A grey model GM (1,1) was built based on a measurement survey of tunnel rock mass convergence. The results showed that the values predicted by the grey model agreed well with the measured ones, and this study can be used as a basis for decision making regarding the observational design and information-based construction of tunnels.%文章根据隧道围岩收敛监测信息,应用灰色系统原理和方法,建立了GM(1,1)模型并进行了预测.预测结果表明,灰色模型预测值与实测值吻合程度较好,能为隧道的动态设计和信息化施工提供决策依据.
