高速公路隧道施工辅助通道设计

Design of Auxiliary Channels for Tunnels

施工工期是工程施工过程中一个比较重要的时间因素,在工期紧张的情况下增加工作面是经常采取的方法。以二广高速公路某隧道为例,通过对隧道出口端增设施工辅助通道,解决现场无法施作施工便道进洞施工的难题,为隧道工程的按时贯通提供了保证,具有较高的效益,可供类似隧道工程设计施工参考应用。

The construction period is an important factor in the process of construction,increasing the working face in the situations of tight working period has been often adopted. In this paper,taking one tunnel of the Er′guang Expressway as an example,through adding an auxiliary construction channel on the exit end of the tunnel, to solve the problem of commencement of the other tunnel,which has provided a strong guarantee for the on time completion of the tunnel working,which has also high efficiency and could be used as references for design and construction of similar tunnels.
