摘要
水库扩建工程与新建工程存在一些技术差异。结合英那河水库大型混凝土砌石重力坝加高培厚工程实践,介绍了该工程导流方案的设计和优化、开挖、新老结合面的技术处理及采取的温控措施等,供类似工程参考。
There were some differences between expansion and new construction projects.This paper,combined with the expansion of large concrete masonry gravity dam on Yingna river,introduced some key technical points such as design and optimization of the diversion,excavation,the treatment of interface and temperature control,for reference.
