摘　　要：从网平差角度研究两相邻图幅的重叠测线间拼接问题,提出3种组网平差模型和图幅间系统误差的判定方法,并通过实例计算比较了组网平差判定法和常用的重叠线直接比对法,计算结果表明,组网平差判定法克服了常用的直接比对法对重叠测线依赖,能有效准确地判定图幅间的系统差异,为测深网拼接提供了更为实用的方法。In terms of practices of one sounding net comparised with adjacent net, three method based adjustment model to judge the systematic errors between two adjacent nets are presentted here. Contrast to the common method, comparsion of two sounding lines in overlapped area of two adjacent nets, the applications of the three methods in real data prove that they can find the systematic errors between two nets effectively and exactly.
