摘要
城市地下空间的开发利用,使得市政工程建设中隧道盖挖施工工程越来越普遍。其中半明挖半盖挖施工相比全盖挖法和明挖法而言,具有其显著的优势。通过对半明挖半盖挖支护体系设计的介绍,指出半明挖半盖挖施工既可确保车辆通行又可通过明挖部分进行材料倒运及混凝土浇筑,该工法既缓解施工空间和作业空间狭小问题,又提高工作效率,缩短施工周期,还节省投资,是值得推广的施工方法。
The development and utilization of urban underground space makes the construction of tunnel cover and excavation more and more common in the construction of municipal engineering. Compared with the full cover excavation method and the clear excavation method,the semi cut and half cover excavation has its remarkable advantages. The design of semi cut and half cover excavation support system is introduced. Semi cut and half cover construction can ensure the traffic of the social and internal vehicles,and the material handling and concrete pouring through the excavation part. This method is to alleviate the small problem of construction space and operation space,and improve work efficiency,shorten the construction period and save investment.
