摘　　要：为了满足测区进行大比例尺地形图(或工程测量)的需要,测区平面控制网(点)的基础上进行加密,除了导线测量方法以外,三角测量是一种较好的可行方法。本文着重介绍了测边三角网平差坐标的解算理论依据及三角网平差的精度评定。In order to meet the test area for large-scale topographic map（or engineering survey） needs,the measured horizontal control area network（point） has been encryption,except the wire measurement method,the triangulation is also a good and workable ways.This article mainly introduced solver theorety basis and triangulation adjustment accuracy assessment of the measurement side triangle network Coordinate adjustment.
