seismic ray paths

It is theoretically proved that when a seismic ray trajectory is a straight line on an interface it may be a curve on another interface.

根据Snell定律提出了透射射线的非线性效应的概念,从理论上证明了当地震射线的轨迹在1个界面上为1条直线时在另1个界面上可为1条曲线;并进一步通过射线追踪实验证明:当地下介质为非水平层状介质时,即使对应于地面同一条直线段上的接收点,来自地下同一个界面上的反射点的轨迹仍可为一条曲线。

Taking the effect of the stability of the eject rock field in a mine on the calamity of mine as an example,this paper applies the high consistency resistance rate method and engineering earthquake reflect method to the supervisory control and reconnaissance of mine geologic disasters.

以某矿山排石场稳定性对矿山地质灾害的影响为例,将高密度电阻率法及工程地震反射法同时应用于矿山地质灾害进行监控和勘察中,结果表明:对于可能引起排石场地质灾害隐患的调查,两种物探方法相结合,相互补充,消除了单一方法的多解性,得到的勘探结果更加准确可靠。
