隧道纵向非一致地震反应的三维数值分析
|
摘要
本文梳理了成层地基非一致地震反应的一维化时域算法和波动输入理论,完善非一致地震反应场地的三维数值模拟技术,据此建立地基-地下隧道系统纵向动力反应数值模型。通过编制FORTRAN辅助程序并借助有限元软件ANSYS,实现上述动力模型的数值计算技术,数值算例验证了其精度和有效性。该套方法为开展非一致地震作用下隧道的纵向行波效应分析,隧道结构精细化数值模拟以及隧道纵向抗震机理等研究课题奠定了基础。
By hackling both the 1D time domain finite element method used to calculate the free field wave motion in elastic layered half space and the theory of wave input,the three dimensional numerical simulation technique for the site asynchronous earthquake response is consummated and then the soil-tunnel structure interaction model is established. Through compiling FORTRAN program combined with finite element software ANSYS,3D numerical simulation of the above whole system is achieved,and its accuracy and validity are proved by numerical examples.The study outcome will be beneficial to further research on the traveling wave effect,refined nonlinear numerical analysis and seismic response mechanism of tunnel structures under asynchronous earthquake motion.
