| 为合理掌握隧道涌水段的大变形成因及其后续危险性发展特征,该文以隧道涌水段事故为工程背景,先结合变形监测成果及地质条件,开展大变形特征分析及其成因分析,并进一步通过变形预测来评价了涌水段的后续危险性发展趋势。实例分析表明：隧道涌水段的大变形特征显著,其成因相对较多,主要包括地形地貌成因、地质构造成因、地下水发育成因、施工扰动成因及爆破扰动成因,各成因相互关联,耦合程度相对较高,共同作用致使了大变形事故的发生；同时,预测结果显示,涌水段后续变形速率仍较大,并无收敛趋势,存在较大的危险性,建议仍需尽快采取加固措施。 |

| In order to reasonably grasp the cause of large deformation and its subsequent dangerous development characteristics of the tunnel water inrush section, this paper takes the tunnel water inrush section accident as the engineering background, first combines the deformation monitoring results and geological conditions, carries out the large deformation feature analysis and its cause analysis, and further evaluates the subsequent dangerous development trend of the water inrush section through deformation prediction. The case analysis shows that the characteristics of large deformation in the water gushing section of the tunnel are significant, and the causes are relatively many, mainly including the causes of topography and geomorphology, geological structure, groundwater development, construction disturbance and blasting disturbance. The causes are interrelated, and the coupling degree is relatively high. The joint action has led to the occurrence of large deformation accidents; At the same time, the prediction results show that the subsequent deformation rate of the water inrush section is still large, and there is no convergence trend. There is a great risk. It is recommended that reinforcement measures should be taken as soon as possible. |
