摘　　要：白鹤滩水电站尾水调压室单体直径和洞群规模均位居世界第一,井身段最大衬砌高度88.5m,对现场施工组织和安全管理提出了极大的挑战。调压室井身段混凝土衬砌通过高压泵送直接入仓、施工排架分层搭设、多维曲面定型酸洗板钢模板以及悬挑现浇牛腿整体反吊浇筑等施工技术,实现了安全、优质和高效施工,为电站首批机组投产发电创造了有利条件。The monomer diameter and tunnel group size of tailwater surge chamber of Baihetan Hydropower Station rank first in the world.Its maximum lining height is 88.5m.This poses a great challenge to on-site construction organization and safety management.Concrete lining of surge chamber shaft section realizes safe,high-quality and high-efficiency construction through high-pressure pumping,layered erection of construction benches,steel form of multi-dimensional curved shaped pickling plate and integral anti-lifting pouring of cantilevered cast-in-situ brackets,which creates favorable conditions for the first batch of units to put into operation and generate electricity.
