| 摘 要： | 文献［１］阐述了地面ＧＰＳ网对隧道横向贯通误差的影响。但是，在大多数情况下，洞口控制网不是单一的ＧＰＳ网，而是ＧＰＳ网与其它形式布设的控制网组成的混合网。这种混合型洞口控制网对隧道横向贯通误差的影响分析，即是本文讨论的内容。

| Abstract: | The literature (1) expounded the influence of GPS network at the exit on precision of the lateral link-up. In the majority, the control network at exit is not GPS network, but the mixed network is used formed by GPS network and conventional network. The paper analyses the influence of the mixed control network at exit on the precision of the lateral link-up. |
