| 摘 要： | 宜巴高速公路界岭隧道施工中,由于复杂的地质状况和处理坍塌历时过长,整个隧道工程严重滞后建设项目工期。因此,决定增设横洞,从横洞向正洞掘进,增加主洞工作面,以满足项目建设进度要求。文章详细介绍了增设横洞两种方案的施工工艺,在技术可行、经济合理基础上,针对界岭隧道横洞垂直贯穿进入正洞和曲线渐变过渡施工转入正洞的施工方案进行了分析对比。

| Abstract: | The construction of the Jieling Tunnel on the Yiba Expressway was behind schedule due to complicated geological conditions that required prolonged treatments of collapse areas.In this case it was decided to add horizontal adits in order to modify the exposed working face.In this article,the two schemes of construction technology for horizontal adits are introduced and an analysis and comparison of the schemes of vertical passing and curved transition are addressed in terms of technical feasibility and economic viability. |
