隧道断层涌水段施工技术分析与实施

Analysis and Implementation of Construction Technology for Fault Water Gushing Section in Tunnel

随着全国路网建设的发展与完善,高速公路、高铁等快速交通设施建设日益兴盛。工程建设过程中,山地区隧道施工难度巨大,不可控因素较多,尤其遇到隧道涌水等特殊地段施工更是面临施工质量与安全的挑战,给工程进度和施工成本控制带来不确定性。以云南省晋红高速光山1号隧道涌水段施工为背景,从现场涌水段施工处置流程阐释特殊地质条件下施工技术要点。

With the development and improvement of national road network construction,the construction of high-speed and high-speed transportation facilities is flourishing day by day.During the construction process of the project,the tunnel construction in mountainous area is very difficult and there are many uncontrollable factors.Especially in the special section of water gushing of tunnel,the construction quality and safety are challenged,which brings uncertainties to the project progress and construction cost control.Based on the construction of water gushing section of No.1 Guangshan Tunnel of Jinhong High Speed in Yunnan Province,this paper explains the key construction techniques under special geological conditions from the construction disposal process of water gushing section on site.
