长距离浅埋洞室典型工程地质问题研究与分析

Research and analysis of typical engineering geological problems in long distance shallow underground excavation

本文以某长距离输水隧洞工程为背景,针对穿越长距离浅埋段,地面同时有河谷、铁路、高速公路、省级公路的复杂地形和地质条件特点,通过工程地质勘察,对该段浅埋洞室的成洞条件和穿越各地表建筑物将遇到的工程地质问题进行了深入研究与分析,提出了工程处理措施和建议,为长距离浅埋洞室顺利施工提供有力技术支撑。

Take a certain long distance water conveyance tunnel as example,the characteristic of water conveyance tunnel have the following characteristics：crossing shallow-buried section,complex terrain and geologic condition which have valley,railway,highway,provincial road.The status of cavitation and engineering geological problems when crossing surface buildings were analyzed,and proposed treatment measures and proposals.This paper provides technical support for the construction of long distance shallow underground excavation.
