摘　　要：受“白格”堰塞湖、“新冠”疫情和预应力锚索工程量增加等诸多因素影响,巴塘水电站导流洞进口按期导流存在较大困难。该工程的导流洞工程和泄洪放空洞工程采用高低洞布置,可分期规划完成相应导流项目的施工。介绍了针对工程边坡采取的调整预应力锚索造孔工艺,四层预应力锚索分期施工、分期张拉和流水作业等工程技术措施,导流洞进水塔混凝土与金属结构安装采取了分期施工技术措施,提前实现了导流洞分流目标。Affected by many factors such as Baige Barrier Lake,COVID-19 epidemic and the increase of pre-stressed anchor cable,it is quite difficult to complete the diversion tunnel of Batang Hydropower Station on schedule.The diversion tunnel and flood discharge tunnel are arranged at high and low levels and the corresponding construction of diversion structures can be completed in stages.This paper introduces the anchor hole forming method on slop through adjusting pre-tension cables,tensioning and streamline construction of four layers of pre-stressed cable in stages,and concreting of intake tower of diversion tunnel and installation of steel structures in stages,which enables the realization of earlier diversion.
