菩萨岗隧道位于地震基本烈度Ⅸ度区,采用时程分析法对隧道结构进行抗震受力分析,据以验算地层的稳定性,并根据分析结果进行隧道结构截面设计,本文对高烈度区域隧道衬砌设计具有参考借鉴作用。
The Bodhisattva tunnel is located in the Ⅸ degree area of the basic seismic intensity. The seismic analysis of the tunnel structure is carried out by time-history analysis. The stability of the stratum is verified and the cross-section of the tunnel structure is designed according to the analysis results. Design has a reference for reference.
