强地震区高拱坝抗震配筋问题

在强地震区建造高拱坝，为减小地震时横缝的张开度，增强坝的整体性，有必要在拱和梁两个方面配置适当的钢筋，但拱向钢筋跨越拱坝横缝，在接缝灌浆前的人工冷却阶段，要求横缝能充分张开，而在地震时，希望横缝的张开度不要太大，这两项要求互相矛盾。为此，提出一种新的设计准则和计算方法，兼顾两方面的要求来进行钢筋的设计。

Design of steel reinforcement across transverse joint in arch dam to resist strong earthquake

It is necessary to put steel reinforcement in the direction of arch and cantilever in the arch dam for resisting strong earthquake The steel reinforcement in the direction of arch will cross the transverse joint In the process of artificial cooling of dam body before grouting of joint, the joint must open fully Under the action of earthquake, the opening of the joint must be as small as possible There is contradiction between the above two requirements A method is offered in this paper to overcome this contradiction in the design of steel reinforcement across transverse joint of arch dam to resist strong earthquake
