在闸门井设计中,不可避免会涉及到抗外压设计问题,一些闸门井孔口部位的跨度较大,使得在不考虑与围岩的联合承载时,闸门井孔口部位两侧井壁结构的内力及配筋结果较大,按该结果进行配筋是很不经济的。以额勒赛下游水电站上电站工程泄洪放空洞闸门井为例,通过考虑围岩与混凝土的联合作用,大大减小了井身结构配筋,为类似的闸门井结构设计提供参考。 In the design of gate wells, it is inevitable to deal with the problem of anti-external pressure design. Some of the gate wells have large spans, so that when the joint bearing with the surrounding rock is not taken into consideration, The internal force and reinforcement results are larger, according to the results of reinforcement is very uneconomical. Taking the flood discharge hole gate well in the downstream power station of EolSai hydropower station as an example, by considering the joint action of surrounding rock and concrete, the well structure reinforcement is greatly reduced, providing reference for similar gate well structure design.
