摘要
江西省峡江水利枢纽工程主体土建Ⅲ标工程由于船闸特大断层、泄水闸断层等不良地质条件影响,开挖工程量和开挖难度大大增加,导致该阶段围堰防护的施工工期严重滞后。为了给工程争取1个月的施工时间,根据区域水文气象条件和赣江水情,通过将原有的二期枯水1号围堰改线并与三期混凝土纵向围堰相接,提高堰顶高程等措施,达到增加河床过流断面,提高度汛标准,工程实现了安全度汛。
The third bidding segment of the civil engineering in Xiajiang Hydro-junction project is added very much in quantities and difficulty of excavation.So construction of the cofferdam in this stage lags behind schedule.To win the project construction time of a month,based on hydro-meteorological condition and Ganjiang river water level,by changing the no.1 cofferdam＇s line,connecting the cofferdam with longitudinal concrete cofferdam in stage 3 and improving elevation of the cofferdam top,the flowing section of the river can be increased to ensure the project can be constructed safely.
