Arrangement structure of gate pier and fishtail pier
The invention belongs to the technical field of water conservancy and hydropower engineering, and particularly discloses an arrangement structure of a gate pier and a fishtail pier. The arrangement structure aims to solve the problems that an existing arrangement structure is poor in integrity, and the fishtail pier is prone to being impacted by floating objects, water flow pulsating pressure and the like. According to the arrangement structure of the gate pier and the fishtail pier, the fishtail pier and the gate pier are arranged into a whole, the fishtail pier is arranged on a first slope section of a gate bottom plate, and the distance between the fishtail pier and a bottom plate structure seam is 0.9-1.1m, so that the integrity of the arrangement structure of the gate pier and the fishtail pier is improved under the condition that the related standard requirements of foundation differential settlement are met, the constraint of the fishtail pier in all directions is increased, and the large bending moment of the bottom foundation of the fishtail pier is homogenized; and the frequency and amplitude of reciprocating vibration of the fishtail pier under the action of the water flow pulsating pressure can be reduced, the impact resistance and high-speed water flow pulsating pressure damage resistance of the fishtail pier are improved, and therefore the possibility of local damage and even toppling of the fishtail pier is reduced.
本发明属于水利水电工程技术领域，具体公开了一种闸墩和鱼尾墩的布置结构，旨在解决现有布置结构的整体性不好，且鱼尾墩易被漂浮物撞击、水流脉动压力等破坏的问题。该闸墩和鱼尾墩的布置结构通过将鱼尾墩与闸墩设置一体，并将鱼尾墩设置在闸底板的第一斜坡段上，且使鱼尾墩与底板结构缝相距0.9～1.1m，这样不仅可以在满足基础不均匀沉降的相关规范要求下，提高闸墩和鱼尾墩布置结构的整体性，增加鱼尾墩的各向约束，均化鱼尾墩底部基础的较大弯矩，而且还可以降低水流脉动压力作用下鱼尾墩的往复振动的频率和幅度，增加鱼尾墩抗撞击和高速水流脉动压力破坏的能力，从而降低鱼尾墩局部损坏甚至倾倒的可能性。
