我们利用[1]中介绍的单层界面反射波的近似公式,用719机计算了一批地震理论模型。暂时的目的是为了验证用所得波动方程近似公式计算理论模型是否相宜,结果时距曲线与射线方程所得的一致,能量曲线与已有资料[2]基本一致,也增加了一些新情况。计算结果如下。一、单炮点水平界面模型设计如图1。界面中心置于剖面中间桩号30处,分别在桩号30(离原点0为3km)、40、50和60处放炮,在0～60桩号(6km长)的剖面段上接收。每种界面长度
Using the approximate formula of the single-layer interface reflection wave introduced in [1], we calculated a number of seismic theoretical models using the 719 machine. The purpose of the interim is to verify whether the theoretical model is calculated by using the approximate formula of the wave equation obtained. The result is consistent with that obtained from the ray equation. The energy curve is basically the same as the existing data [2], and some new situations are added. The calculation results are as follows. First, the single-shot horizontal interface model design shown in Figure 1. The center of the interface is placed at 30 middle stakes in the section, and shots are made at station 30 (3km from zero point 0), 40, 50 and 60 and on section 0 to 60 (6km) respectively. The length of each interface
