超长管棚施工技术在山岭隧道软弱围岩中的应用

Application of Ultra Long Pipe Shed Construction Technology in Weak Surrounding Rock of Mountain Tunnel

摘要:

以黄衢南高速公路阳排尖隧道为例，介绍了大于30 m超长管棚施工技术;并根据现场监控量测数据，对左右洞不同管棚施工技术效果进行对比分析；分析结果显示，一次性施作超长管棚在山岭隧道软弱围岩地段有较好的实用性。

Abstract:

Based on Yangpaijian tunnel of Huangqunan highway, this paper introduces construction technologies of more than 30 meters ultra long pipe shed, and comparatively analyses the different pipe shed construction for left and right route by the site-monitored data. The results show that one-time construction of ultra long pipe shed can be effectively applied in weak surrounding rock of mountain tunnel.
