| 摘 要： | 在进行隧道施工时，应根据围岩实际情况确定支护参数，并制定切实可行的施工方案，防止沉降、收敛等变形的产生。隧道变形一旦产生，需要进行换拱施工时，应先进行支撑加固防止坍塌事故的发生，确保施工安全及质量。

| Abstract: | Supporting parameters should be determined according to the actual situation of surrounding before we excavate the tunnel, and develop practical construction program to prevent subsidence and convergence distortions. It is necessany for arch construction to support the reinforcement to prevent collapse to ensure construction safety and quality once tunnel deformation generated. |
