摘　　要：在物探测量过程中,地震测线如何避让地下障碍设施成为安全和按时完成地震采集任务必须解决的难题。本文介绍一种根据布尔沙模型的原理,利用坐标转换的方法,将地下障碍的位置准确展现出来,对炮点和检波点做变换观测系统的设计。通过多个施工区域的地下障碍的坐标转换,证明了其可靠性和实用性。How to avoid underground obstacles in seismic survey line,Has become a safe and timely completion of the seismic acquisition task must solve the problem.According to the principle of Boolean sand model,using the coordinate transformation method,could accurately show the position of the underground obstacles,the shot point and the detection point do transformation design of observation system.Through multiple construction area underground obstacles of coordinate transformation,has proved its reliability and practicability.
