以荣(成)乌(海)高速公路抢风岭隧道为例,介绍了在复杂地质条件下特长隧道开通施工斜井的必要性、斜井施工的特点与难点。从选址、方案比选、参数设计、经济合理性、防排水防护、下穿省道、交叉口施工及协调工作面等方面,对斜井施工方法及控制要点进行了详细论述。结果表明,施工质量得到保证,工期进一步缩短。
Taking the example of the Goufengling Tunnel of Rong (Cheng) U (sea) Expressway for an example, the necessity of incline construction of special long tunnel under complicated geological conditions and the characteristics and difficulties of inclined shaft construction are introduced. From the aspects of site selection, plan selection, parameter design, economic rationality, water and drainage protection, underpass, intersection construction and coordination of work surfaces, etc., the construction methods and control points of inclined shafts are discussed in detail. The results show that construction quality is guaranteed and construction period is further shortened.
