| 摘 要： | 垂直地震剖面(VSP)是一种有效地进行工程地质调查的方法技术。本文根据工程勘查的特点,从正演模拟问题入手,结合上海市第二越江隧道工程VSP勘查实例,讨论了工程VSP方法技术和应用效果,使用了多道井下仪器和电火花震源开展工作。在资料处理中,使用两次f-k滤波可有效地分离上、下行波场。

| Abstract: | Vertical seismic profile ( VSP ) is an effective method for engineering geological investigation. The paper begins with the forward modeling problem based on character of the investigation and then discusses the technique and application effects of engineering VSP as examplified by the VSP investigation of the second tunnel through the Huangpu River in Shanghai. The utilization of downhole multi channel instrument and electrical spark source helps to carry out the VSP investigation. Double f-k filtering can effectively separate up and down going wave fields in date processing. |
