以某公路大跨隧道为背景介绍了在隧道开挖过程中围岩压力及变形受开挖影响所产生的变化，通过对实测数据的分析，指导施工中支护参数的调整，与理论公式进行对比选定合理的公式、确定准确的地质参数，预测下段施工围岩压力及变化。

Taking a largespanned tunnel on a highway as an example, the article describes the variations of the pressures and deformations of the surrounding rock mass caused by the tunnel excavation. By means of analysis on the measured data, guidance is provided for the adjustment of the reinforcement parameters during the tunnel construction. By means of comparison with the theoretical formulas, proper formulas are selected, accurate geological parameters are determined and the pressures and changes of the surrounding rock mass ahead of the working face are predicted.
