摘要
研究了地基表面在刚性动力荷载作用下的动力反应,给出了柱坐标解。在此基础上获得一个实用的地基动力刚度。定性地讨论了地基刚度和阻尼及其相互关系。并提出一个求取地基动力刚度和粘滞系数的实用化方法。
The dynamic response of the ground under the action of a rigid circular dynamic loading is studied. Cylindrical solutions are given. Based on the solutions, a practical dynamic ground rigidity is presented. Dynamic rigidity and damping coefficient of the ground and their relation are also discussed qualitatively. A practical method is presented for determination of the dynamic rigidity and damping coefficient.
