小断面隧道施工中出碴点的设置

Set-up of Slag Point in Construction of Small Section Tunnel

本文结合隧道施工特点,分析了出碴对工期的影响,针对小断面隧道内出碴点设置情况进行了分析对比,建立了设置合理数量的出碴点数学计算模型,通过设置优化程序,为确立出碴点个数及位置提供了定量评估手段。

The influence of slag production on construction term was analyzed based on the characteristic of tunnel construction. A reasonable calculation model of slag point was built according to slag point seting in small section tunnel project. Some appraisal ways were given too.
