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

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.
