磁法勘探解析延拓算法在探测地下洞穴中的应用

The Application of the Analytical Continuation Algorithm of Magnetic Prospecting in Underground Cave Exploration

通过对某地下防空洞探测的磁异常数据的研究，以解析延拓的方法作了向上与向下的延拓．结果表明：解析延拓算法的研究，对确定地下异常体与更精确圈定其几何形态是非常有效的．

In this essay,the magnetic field data,which is surveied on the surface of an airraid shelter,is studied with the upward and downward method of analytic continuation.The results indicate that the study of analytic continuation is very effective to delimit the underground geologic body and more precisely delimit the body's geometric status.
