摘要
为了解地下结构在瞬态地震波作用下的位移及加速度等情况,利用有限元法分析了瞬态水平偏振横波(horizonally-polarized shear wave,简称SH波)作用下孔边动应力集中问题,建立了波动有限元模型,对用有限元法模拟实际波动进行了探讨,利用通用有限元软件ANSYS对瞬态SH波作用下孔边动应力集中系数进行了计算,并与解析解进行了对比。
In order to obtain the displacement and accelerate of underground structure effected by transient seismic wave, the issue of the cavity stress concentration by transient SH-wave in FEM was analyzed, the model of wave finite element was founded, rationality of this method was discussed, the dynamic stress concentration factor at the edge of the cavity was calculated by ANSYS program and the result was compared to the resolution.
