新疆某水电站引水渠排洪涵洞修补加固方案

新疆某水电站引水渠的跨洪沟箱涵由于顶板和底板配筋不足．使得正截面受弯承载力和斜截面受剪承载力不够，导致排洪箱涵顶板和底板出现受弯和受剪裂缝。通过对箱涵裂缝进行细致的调查，提出了修补方案，并对箱涵结构内力、配筋及过洪能力等进行了复核计算，使得箱涵结构满足安全运行要求。

Culvert Repair Reinforcement Scheme of a Certain Hydropower Station Diversion Channels in Xinjiang

A certain hydropower station diversion channels across hong ditch of Xinjiang box culvert caused by a lack of roof and floor reinforcement, makes the fiexural bearing capacity of normal section and inclined section shear bearing capacity is not enough, lead to having box culvert top and bottom of the bending and shear cracks. Through the detailed in- vestigation, and cracks in box culvert repair scheme is proposed, and the internal forces of box culvert structure, reinforcement calculation and flood capacity and so on has carried on the review, makes the box culvert structure satisfies the requirement of safe operation.
