摘要
渫水皂市水利枢纽左岸上坝公路鹰嘴岩隧道围岩主要为Ⅱ、Ⅲ、Ⅳ、Ⅴ类围岩,地质条件复杂,成洞条件差。在隧道施工中,遵循"短进尺,弱爆破、少扰动、早支护"的原则,及时进行监控量测,采取有效的加固措施,取得了良好效果,确保了工程进度与安全。
The surrounding rocks of the Yingzuiyan Tunnel of the access road on the left bank of the Dieshui City Water Control Project mainly consists of the classII, III, IV and V rocks which have complex geological conditions and bad tunnelforming conditions. In the construction of the tunnel, we followed the principle 'short feeding, weak blasting, less disturbing and early support', made timely supervision and measurement and adopted effective fastening measures so that better results were obtained and the progress and safety of the project were ensured.
