摘要
象鼻岭水电站引水发电系统采用地下洞室群的布置方式,洞室较多,其土建施工方式具有显著的地区特点,总体施工比较复杂,尤其是关键部位的施工成为推进工程进展的制约因素。为此,在分析了工程特点、施工重难点的基础上,系统概括总结、提炼了多个关键部位开挖、支护、混凝土施工的主要施工方法和质量控制措施。实践证明:其方法、措施可行,经验可供类似工程施工参考。
The power diversion system of Xiangbiling Hydropower Project is designed with multiple underground tunnels and chambers, which leads to civil construction is relatively complicate with distinct regional feature, and construction of key positions is constraints on the progress of project. Analysis was made on the features of project and difficulties of construction, based on which the authors summarize the major construction methods and quality control measures for the excavation, support and concreting at key positions.
