掌鸠河引水供水工程过普渡河大断裂措施研究与设计

Measure Research and Design for Passing through Puduhe Fault of Zhangjiu River Water Diversion and Supply Project

掌鸠河引水供水工程输水线路南段大部分输水建筑物处于或接近普渡河大断裂带,通过设置带有伸缩节、滑动支座、固定球型摆动支座的洞内明钢管道,很好地解决了大断裂带建筑物的变位问题。经过通水试验和实际运行表明,设计安全系数及采取的处理措施是安全可靠、经济合理的,可供类似工程借鉴。

The water diversion structures of south section of Zhangjiu River Water Diversion and Supply Project locate near or pass through the Pudehe Fault. The deformation problem of structures is solved by the design of exposed steel pipe arranged in tunnel with expansion joints, sliding ring girder supports and fixed spherical rocking ring girder supports. The water-filled tests and actual operation show that the design safety factor and treatment is practical and economical and can be as references to similar projects.
