| 摘 要： | 通过对某工程场地采用不同的介质参数和不同的人工边界处理方法求得的地面运动的比较，指出，只有应用合理的计算模型才得到正确的计算结果，文章还对在均匀粘弹性半空间内任意划定刚性和滚轴人工边界造成的计算误差作了探讨。

| Abstract: | Different medium parameters and artificial boundary conditions are used to deal with the ground motion of a engineering site. The results of different conditions are obtained and compared. It is showed that the rational conclusions are based on the reasonable calculation model. It is also analyzed the error caused by random stipulation of rigid or roller bearing artificial boundary in the uniform viscoelastic half-space. |
