摘要:
采用复变函数、Green函数方法研究了SH波作用下,地下圆形衬砌与多个裂纹复合缺陷的地震动问题。求解关键是构造适合所需的Green函数,即含圆形衬砌的弹性半空间内任意一点承受时间谐和的出平面线源荷载的位移函数的基本解。再结合裂纹"切割"方法在任意位置上构造多个任意长度的裂纹,求得圆形衬砌和多个裂纹同时存在情况下的位移场与应力场。最后通过算例,进一步探讨不同参数对水平地表地震动的影响规律。
Abstract:
Ground motion of underground circular lining structure and multiple cracks under SH-waves was reported using the methods of complex variables function and Green’s function. The key point is to construct a Green’s function, namely an essential solution of the displacement field for the elastic half-space containing circular lining structure while bearing out-plane harmonic line source loads in half space at arbitrary point. The method of "crack-division" is developed to establish the cracks, then the expressions of displacement and stress can be obtained while the circular lining structure and cracks are both in existent. Finally, numerical examples are provided to discuss the influence of different parameters upon the horizontal surface displacement.
