竖井联系四边形测量及其精度分析

Shaft Connection Survey and the Analysis of the Precision

本文结合施测现场狭小等实际情况,运用竖井联系测量原理,在一井定向中合理的进行井下及井上布点方案设计,采取增加连接点形成了联系四边形图形,同时运用全站仪测距及导高等一系列技术方法进行规范化施测,最后对其定向精度进行精度分析,分析所得的精度完全满足竖井测量生产实践的需要。实践证明,该测量方法是一种简便、快捷、低成本、高精度的方法,为同类工程提供一定的技术支持。

The layout scheme is designed in a directional well, which is taken to increase the connection point measures formed contact quadrilateral graphics, while the use of a series of technical method and safeguard measures standardized test, such as total station location and guide higher .then the orientation precision of estimation and analysis is taken. The practice shows that the method is simple, fast, low cost and high precision. It is worth using for reference.
