| 摘 要： | 建立了土钉土体系统动力计算模型，这种模型将土体对土钉的作用处理成一
个线性弹簧和一个与速度有关的阻尼器，把面板对土钉的惯性作用简化为集中于土钉头上的
等效质量加以考虑. 以此为基础，建立土钉土体系统地震动力作用下的阻尼微分方程，求解
了在简谐地震作用下土钉动力响应的解析解. 最后，结合一案例进行了分析，并用大型非线
性有限元软件ADINA对此计算模型进行了验证，结果表明这种计算模型对土质较均匀的边坡
动力设计和分析是安全、可靠、合理的.

| Abstract: | A dynamic calculation model of soil nailing structure for slope protection is proposed in the present paper.The interaction between soil and soil nailing is treated as linear spring and damping system related to velocity.The inertia of the facing upon soil nailing is simplified as an equivalent concentrated mass.Excitation equations of vibration response under horizontal harmonic earthquake are established,and the analytical solutions are obtained for steady vibration.3D nonlinear FEM with ADINA software is... |
