摘要
本文较详细地介绍了重力垂直梯度测量探测岩溶的基本原理和野外工作及资料整理方法;并对重力垂直梯度测量的观测误差及最佳仪器高差的选择进行了较深入的探讨。文章从大量的生产和试验成果中,筛选出一些资料较完整、较典型的实例,论证了高精度重力垂直梯度测量技术在岩溶区不同地质环境中,探不测溶(土)洞的可行性及效果。
Tt is a new area that the vertical gravity gradient is applied to prospect hidden karst in our country. The basic principle, field application and data processing method of the vertical gravity gradient survey are introduced in this paper. In addition, the survey error and the optimum difference of instrument altitude are discussed. The typical examples selected from a lot of field applications and trial results have proved that it is effective and better using the vertical gravity gradient method to detect solution cave and soil cavity in various karst regins.
