| Abstract: | The geological structure and hydrogeological conditions of the newly built Hanshi railway Xiangyang Xianshan No. 1 tunnel is complex, and the stability of surrounding rock of grade V is poor. The three-bench seven-step excavation method and controlled blasting technology adopted in the engineering tunneling have optimized the parameters of blasting excavation, and ensured the efficient and orderly tunneling under the good blasting effect. It can provide reference for large cross-section engineering with similar geological conditions. |
