秦岭天台山隧道通风竖井施工技术与管理措施

Study on Construction Technology and Management Measure of Ventilation Shaft for Qinling Tiantai Mountain Tunnel

以秦岭天台山隧道通风竖井为工程背景,本文综合各种因素提出了一套合理的竖井掘进施工技术和管理措施,并深入和系统地阐述了本工程井筒锁口施工,掘进施工,装岩与提升,初期支护,二次衬砌施工的施工工艺与流程与施工管理措施。本文的研究成果可为后续的深埋隧道通风竖井和同类工程提供经验和借鉴。

In this paper,a set of reasonable construction scheme and management measure for excavation of shaft is developed based on various factors,taking ventilation shaft of Tiantai Mountain tunnel in Qinling Mountains as engineering background.And the construction technology and process of shaft locking construction,tunneling construction,rock loading and lifting,initial support,and secondary lining construction was expounded in-depth and systematically in this project.The research results of this paper can provide experience and reference for the follow-up deep-buried tunnel ventilation shafts and similar projects.
