采用状态空间精细法计算弹性地基板的动力响应量。对空间域采用有限元计算，对时间域采用状态空间精细法。在计算过程中，不解线性方程组，直接进行精细迭代计算，程序简单，效率高。给出２个数值算例，对数值结果与直接积分法进行了比较，其计算结果比较接近。
The state space fine method was used to calculate the dynamic response of the elastic substrate. Finite element calculations are used for the spatial domain and state space fineness method is used for the time domain. In the calculation process, the linear equations are not solved, and the precise iterative calculation is performed directly. The procedure is simple and the efficiency is high. Two numerical examples are given and the numerical results are compared with the direct integration method. The calculation results are close.
