摘　　要：对于拱形坝,两坝段之间的横缝都要进行灌浆,灌浆后各个坝块连接成一个整体,起整体拱的作用。详细介绍拱坝接缝接触灌浆全过程,对灌浆技术进行分析总结,该拱坝的成功封拱灌浆技术,保证电站尽早蓄水发电,提高了经济效益。采用橡胶拔管,具有质量可靠、经久耐用的优点。For arch dams,grouting is required for the transverse joints between the two sections.After grouting,each dam block is connected as a whole and acts as an integral arch.In this paper,the whole process of contact grouting for arch dam joint is introduced in detail,and grouting technology is analyzed and summarized.The joint closure sealing grouting technology of the arch dam guarantees that the power plant can store water and generate electricity as soon as possible and improves economic benefits.This technology uses rubber tube pulling and has the advantages of reliable quality and durability.
