摘要
拉洛水利工程位于平均海拔4 000 m以上的青藏高原西部地区,临近珠穆朗玛峰。引水隧洞的开挖受制于地质条件,在施工过程中应充分了解地质条件并加以利用,在合理使用施工技术的前提条件下处理地质缺陷带来的各类问题,隧洞开挖缺陷处理方式可归纳为三大措施:封闭、排水和预留保护层。
Tunnel excavation is subject to geological conditions. During the construction of diversion tunnel, more information should be collected in this regard so as to properly deal with problems caused by geological defects on the premise of rational utilization of construction technologies.
