双站观测与距离侧方交会

Dual Station and Distance Lateral Intersection

距离侧方交会是工程测量中常用的方法,特别是全站仪的广泛使用,使得该测量方法的精度大幅度提高。在城市测量中,用全站仪距离侧方交会的方法插入付点来解决测站点不足的问题,是一种方便、准确、可靠的方法。付点作为距离侧方交会的一种特殊形式,有其使用的特点及要求,本文主要介绍了付点的应用环境、注意事项及计算公式,并结合实际对其精度及可靠性作了量化分析。

The mathod of distance lateral intersection is often used in engineering survey,and the pricisionof this method is Substantial improved as extensive used of total station.Using the method of distance lateral intersection and inserting sidepoint to resolve quentions of station in city surveying,this means is convenient,accurate,credible.the method of side-point is a spatial form in distance lateral intersection and needed some used request.In this artical some applied canditions, notices and calculative formulary ared introduced, and some quantizing analysis of precision and reliability are discuss based on combining facts.
