全工序同步平行施工技术在震后特长隧道中的应用

Application of Whole Process Synchronous Parallel Construction Technology on a Super Long Tunnel after Earthquake

特长公路隧道采用传统的施工管理,工作效率低、施工工期长,造成施工成本提高。针对震后映秀特长隧道工期紧、地质条件差、施工繁琐的特点,采用全工序同步平行施工技术。通过严密管理、科学组织,该项施工技术得以顺利进行并取得显著效果,大大缩短工期、降低工程成本,为今后特长隧道施工提供经验借鉴。

The traditional construction management in super long road tunnels may lead to low work efficiency, long construction period and high construction cost. In view of distinguishing features of tight schedule, poor geological conditions and complex construction, the whole process synchronous parallel construction technology has been applied to the super long tunnels after earthquake. This construction technology has achieved remarkable goals due to overall and well-organized management. The construction period has been shortened and the construction cost has been reduced. It can provide experiences for reference in the similar projects.
