摘　　要：在林区及其它通视条件比较困难的地区,由于已知控制点比较少且通视条件受到严格的限制,在进行控制测量时,采用无定向导线的路线布设方式可以解决控制点少、控制点之间不通视问题。利用了附有未知数条件平差原理对无定向导线进行了解算,并对其进行了精度分析,最后用实例证明它是一种高效、快速、经济的线路测量方法,有广泛的应用前景。In the forest and other non-intervisible section, in the control measurement, the non-oriented traverse was adopted to solve less control points and confined intervisibility. In the paper, the principle of conditional adjustment attached unknown was used to solved the problem; the precision of measurement value was analyzed. At last, an example was used to prove it a high efficiency, quick and economic method. It will have a widely foreground.
