摘要
宜万铁路沿线岩溶大量发育,因此采用有效方法探明隐伏岩溶的规模和位置对铁路的运行安全至关重要。本文结合地震映像法在宜万铁路的实践,利用互相关滤波方法对地震资料进行模拟和处理,在较强干扰背景下有效地提取出了地震信号,压制了随机干扰,对岩溶的识别具有一定的指导意义。
With the Karst growing along the Yiwan rail-way, it is important to adopt an effective method and explore the hidden Karst so as to avoid the danger in the tunnels. We use the cross correlation method in seismic data processing to extract the seismic signal with explicit characteristics from noise background, which will offer guidance for identifying the Karst.
