利用上文中所介绍的方法,分析土坝的非线性地震反应,计算反应量的整个时程,其中包括土坝的永久变形。考虑了两个不同的输入地面运动情况:具有不同频率特性的一个中强振动和一个强烈振动。进行了对比的研究,以检验二维、非线性、非均匀性、振
Using the method described above, the nonlinear seismic response of the earth dam is analyzed to calculate the entire time course of the response, including the permanent deformation of the earth dam. Two different input ground motion conditions are considered: a medium-strong vibration and a strong vibration with different frequency characteristics. A comparative study was conducted to examine two-dimensional, non-linear, non-uniformity, vibrations
