浅埋偏压且围岩破碎隧道的施工监控量测

Tunnel Supervision of Construction with Shallow Cover Deviation Press and Surrounding Cracked Rocks

云桂铁路贯穿云贵高原山麓,属于典型的喀斯特地貌,地质状况复杂多变.云桂铁路(云南段)第三标高坡隧道进口具有浅埋偏压且围岩破碎的特点,本文介绍了该隧道施工监控量测方案,对典型监控断面数据进行了分析,为隧道施工提供了重要指导作用.

Yungui railway runs through the foothills of the Yunnan-Guizhou plateau which is the part of typical karst. The geological condition is complex and changing. Shallow cover deviation press and surrounding cracked rocks are the geological features of tunnel in Yungui railway（Yunnan section）. The tunnel construction monitoring measurement program and the data analysis of typical monitoring cross-section are shown in this article,which has been a significant role in guiding tunnel construction.
