频率测深最近几年在国内很多地区开展起来,但实际工作中遇到的许多问题仍未得到解决。众所周知,在复杂地形条件下,频率测深工作较难进行。特别是对于预先设计的物理观测点、发收距和布极方向,如果恰好发射或接收点位于复杂地形上(悬崖、河流等),为了使观测得以进行,通常将发射或接收点平行移动一定的距离,这就使得实际的布极方向偏离设计的轴向或赤道向,给观测结果造成误差。本文讨论了目前广泛应用的电偶源发射时,由于实际布极方向偏离轴向或赤道向时,影响观测结果的程度。
Frequency sounding has been carried out in many areas in recent years in China, but many problems encountered in actual work have not yet been solved. As we all know, in complex terrain conditions, frequency sounding is more difficult to do. Especially for predesigned physical observation points, spans and poles, if the launch or reception point happens to be on a complex terrain (cliffs, rivers, etc.), it is common to move the launch or reception points in parallel for a certain amount of time Distance, which makes the actual direction of the pole deviate from the design of the axial or equatorial, resulting in errors in the observation results. In this paper, we discuss the extent of the observed results when the actual dipole direction deviates from the axial or equatorial direction when the electric dipole source is widely used.
