长大斜井快速施工关键技术

结合雪峰山隧道白沙斜井具有地质条件复杂、长度长、坡度陡、反坡排水、工作面多、施工组织难度大、施工风险多、较一般斜井施工困难等特点,通过对雪峰山隧道白沙斜井快速施工的关键技术进行总结和体会,阐述长大隧道快速施工问题的对策,以期为类似项目提供有益借鉴。

Key Technologies in Fast Construction of Long and Big Inclined Shafts

Baisha Inclined Shaft of Xuefeng Mount.Tunnel is in complicated geological conditions,and has a big length,steep slopes,reversed slope drainage,multiple work surfaces,difficult construction organization and a high construction risk,which cause harder construction compared with other inclined shaft.Through summarization and understanding of key technologies in Baisha Inclined Shaft of Xuefeng Mount.Tunnel,this paper expounds countermeasures for problems in long and big tunnel fast construction,which can be r...
