武汉地铁工程紧邻四孔平行盾构隧道的地震响应分析
|
摘要
针对国内少见的武汉地铁工程紧邻四孔平行盾构隧道,为其评价抗震性能,采用有限元法计算分析了在武汉人工合成波作用下的三维地震响应规律:地震荷载引起隧道结构剪力增幅较大,轴力增幅较小,水平位移最大值仅1.93 cm。计算分析结果表明,紧邻多孔隧道满足抗震要求。
In order to evaluate the earthquake resistance of the domestic rare four parallel adjacent shield tunnels in Wuhan Metro Project,three-dimensional earthquake response of four parallel adjacent tunnels under Wuhan artificial wave were separately analyzed by finite element method.There is a larger increase in tunnel shear strength and a smaller increase in axial force,and the maximum horizontal displacement is only 1.93 cm caused by earthquake load.The calculation results showed that adjacent multiple tunnels satisfied the requirement of earthquake resistance.
