摘要
广东省HY饮水工程的引水隧洞所处地质条件复杂,隧洞开挖后,围岩出现了多种变形现象,如顶拱下沉、底板隆起、侧壁内移、掉块等。就该引水隧洞施工围岩的变形特征进行分析,包括围岩物理力学性质测试、变形机理分析、变形特征影响因素分析等,以保障工程顺利进行。
The geological conditions of the diversion tunnel of Guangdong HY Drinking Water Project are complex.After excavation,various deformation phenomena occur in the surrounding rock,such as sinking of the top arch,uplift of the bottom plate,internal displacement of the side walls,and falling of blocks.This paper analyzes the deformation characteristics of the surrounding rock during the construction of the diversion tunnel,including testing of the physical and mechanical properties of the surrounding rock,analysis of the deformation mechanism,and analysis of the influencing factors of the deformation characteristics,in order to ensure the smooth progress of the project.
