Landslide surge impact resistant gate system design method

The invention discloses a design method of a gate system capable of resisting landslide surge impact, and belongs to the technical field of hydroelectric and hydraulic engineering structures. The gate system comprises a service gate, a plane bulkhead gate, a plane water retaining gate, a plane emergency gate and a water inlet quick gate, and the water retaining state and the operation state of the service gate are designed according to the landslide surge working condition. The water retaining states of the plane bulkhead gate, the plane water retaining gate, the plane emergency gate and the water inlet quick gate are designed according to the landslide surge working condition, and the opening and closing force of the plane bulkhead gate, the plane water retaining gate, the plane emergency gate and the water inlet quick gate is designed according to the normal design water level operation working condition. Corresponding anti-surge design working conditions and structural types are adopted for gates with diff
