【摘要】 从陷落柱的物性基础出发,阐述了利用地震波动法探测陷落柱的可行性,并根据波动方程原理,设计了部分陷落柱数学模型;运用正演模拟的方法,从地震波的运动学和动力学角度出发,分析了不同参数的陷落柱各自的地震响应特征及其分辨率;在前人有关陷落柱研究基础上,进一步研究了陷落柱与地堑的区别。结合实际资料总结了陷落柱在地震资料中的反映特征和识别标志。更多还原

【Abstract】 Based on the physical property of collapsed pole,the thesis formulates the feasibility of detection collapsed pole by seismic reflected wave method and designs mathematical model of partial collapsed pole according to principle of ray tracking and wave equation;analyses each characteristic response of collapsed pole with different parameters by the mean of simulating from the point of view of kinematics and dynamics;Further study is made to distinguish collapsed pole and graben on the grounds of previous research about delayed diffracted wave from collapsedpole.In the end,generalizes the reflection features and identifications of collapsed pole in seismic data linking up with practical material.更多还原
