在ADINA中建立了三维多次透射公式，可以同时模拟地震波的输入和无限域的散射，这与集中质量显式有限元法的进展是一致的。建立了三维立方体模型，输入一个δ脉冲波，将模拟结果与解析解进行比较。仿真结果表明，峰值误差为输入波的0.2%，满足通常数值模拟的要求。该方法在局部场精细模型场地效应分析中具有一定的效率优势。建立了玉溪盆地的速度结构模型，并通过数值模拟研究了盆地效应。聚焦效应的分布与玉溪盆地东西窄南北宽的构造特征有关，边缘效应与盆地基底坡度有关。给出了盆地内地震动放大效应的分布图。
A three-dimensional multitransmitting formula is developed in ADINA to simulate the input of seismic waves and the scattering of infinite domains at the same time, consistent with the progress of the explicit finite element method of lumped mass. A three-dimensional cube model is built, and a delta pulse wave is input to compare the simulation results with the analytical solutions. The simulation results show that the peak error is 0.2% of the input wave, which meets the requirements of the usual numerical simulation. This method has a certain efficiency advantage in site effect analyses of fine models for localized fields. A velocity structure model of the Yuxi Basin is built, and the associated basin effect is studied by numerical simulation. The distribution of the focusing effect is related to the structure of the narrow east-west and wide north-south featuresin the Yuxi Basin, and the edge effect is related to the slope of the basin base. A distribution map is given of the amplification effect of ground motion in the basin.
