摘　　要：在桥梁工程测量中,经常采用测边交会和大地四边形独立网进行控制测量。计算机的广泛使用给测边网平差提供了一种简单的平差方法—AutoCAD作图平差法,这种方法直观、精确,适用于工程测量中的控制测量。In bridge engineering survey, the linear intersection and independent geodic quadrilateral network are often used for control survey. The wide application of computers nowadays makes it possible to provide the trilateration network adjustment with a simple method, that is, the AutoCAD plotting adjustment method. The method is directly visible, accurate and is applicable to the control survey of the bridge engineering.
