SOLUTION OF THE DYNAMIC RESPONSE OF RIGID FOUNDATION OF ARBITRARY SHAPE ON MULTI-LAYERED SOIL

Funds: The project was supported by the Sino-German Science Foundation (GZ566) and the National Natural Science Foundation of China (51138001).
  • 摘要: 提出了基于积分变换、对偶方程与精细积分算法求解多层地基任意形状刚性基础的动力刚度问题. 首先在频率波数域内圆柱坐标体系中利用圆形微元的对称与反对称特性建立多层地基中格林影响函数的波动方程,然后将应力和位移关系表示成对偶形式进行精细积分求解以提高计算精度和稳定性. 再将任意形状刚性基础与地基的交界面离散化为一系列圆形微元,利用格林影响函数建立其平动与转动动力刚度的矩阵方程. 该求解方法高效、准确并且计算稳定,适于任意复杂多层地基任意形状基础动力刚度的计算.
