摘　　要：长大公路隧道首级控制网的稳定性直接关系到隧道施工安全和贯通质量，必须对控制网进行定期复测，以便掌握控制点的稳定性。综合运用平均间隙法和EMBED Equation.3检验作为稳定性判别的方法，对某长大公路隧道GPS平面控制网多次复测成果进行了稳定性计算分析，很好判断了各GPS控制点的稳定状况，对隧道的施工安全和顺利贯通提供了强有力的保障。The stability of the top level control network in the long highway tunnel directly relates to the safety of the tunnel construction and breaking through quality, therefore, regular retest to control network must be conducted in order to master the stability of control points. Firstly, the stability calculation of retest results on GPS horizontal control network in a certain long highway tunnel is analysed many times by the average gap method and inspection as stability judgment, and then the proper judgment for stable status of the GPS control points is worked out, which provides great guarantee in the construction safety and smoothly completion.
