盾构隧道抗震分析近似解析解及其应用
|
摘要
为简化深埋地下结构的抗震分析,基于连续介质福季耶娃法,给出了求解P波和S波共同作用下盾构隧道的近似解析解求解方法,并与福季耶娃法数值解的计算结果进行了比较.结果表明,2种方法获得的内力——弯距和轴力的分布规律基本相同,说明近似解析解可以用于深埋盾构隧道抗震分析,且能大大减小数值计算的复杂性和工作量.
To simplify the aseismic analysis of deeply-buried underground structures,an approximate analytical method considering the common action of P and S waves on shield tunnels was presented based on the Fotieva method for successive medium strata,and a comparison was carried out between the calculational results of bending moment and axial force,obtained respectively by the approximate analytical method and FEM(finite element method) based on the Fotieva method,acting on a deeply-buried underground structure.The comparison result shows that the approximate analytical solutions for bending moment and axial force on deeply-buried underground structures are basically the same as those based on the Fotieva method,indicating that the proposed approximate analytical method can simplify the complexity and workload of aseismic analysis of shield tunnels.
