福州大腹山隧洞围岩位移的非线性时序分析

A nonlinear time series model for surrounding rock displacement of Dafu Mountain Tunnel

以福州大腹山隧洞为例 ,在分析其工程地质条件的基础上 ,对隧洞围岩位移监控量测数据建立了非线性时间序列分析模型 .所建模型可用于预测隧洞围岩位移的未来变化 。

Based on the analysis of the engineering geological condition of Dafu Mountain Tunnel, a nonlinear time series model for the surrounding rock displacement is established. The model can be used for predicting the surrounding rock displacement of the tunnel and evaluating the surrounding rock stability. The nonlinear time series analysis provides a new method for forecasting the surrounding rock displacement by applying displacement back analysis and a useful technique for NATM.
