摘要
根据富蕴县黄泥滩供水工程引水隧洞工程地质特点,分析了围岩应力分布特征和破坏特点,介绍了"新奥地利隧洞施工法"在Ⅳ类围岩体成洞的应用情况和采用的安全保障措施,可为相关工程施工和管理提供借鉴。
Wall rock stress distribution features and damage characteristics are analyzed according to geological characteristics of Diversion Tunnel Engineering in Fuynn County Huangnitan Water Supply Project. The application of ＇ New Austrian Tunnel Construction Method＇ in class IV wall rock cavity formation, and the applied security measures are introduced, thereby providing reference for construction and management of relevant projects.
