测线坐标系在山区常规地震测量中的应用
|
摘要
在复杂山区进行物探测量时,检核每一个物理点的偏移量十分烦琐。本文介绍了一种直接测量点位的方法及其施工过程,通过建立一个假定坐标系,根据无论在哪种类型的坐标中,点与点之间的相对位置都固定不变的概念,进行上线设计,最后测量出每个物理点。实践证明,使用该方法可以在满足物探施工要求的基础上减少工作量,提高工作效率。
During the survey of geophysical exploration in complex mountainous area,checking the stake offsets in each physical point is very tedious.The paper introduced a method of directly measuring point position and construction process:through building up a hypothetical coordinate system,and based on that the relative position between the points is fix in whichever type of coordinate,we carry out the line design,and finally measure each physical point.The practice proved that the method can reduce work efforts and improve work efficiency on the basis of meeting the needs of geophysical construction.
