Sedimentary rock layers are always characterized by a particular seismic response. 沉积岩地区，总是以一种独特的地震响应为特征的。
Some statistic laws are discussed about the gravity dam's seismic responses of accelerations and stresses changing with the dam height and the foundation stiffness. 同时分析了重力坝地震响应加速度和动应力随坝高和坝基刚度变化的统计规律。
