Experimental study and numerical analysis on ship lifter tower structure of Jinghong hydroelectric power project indicate: For those rising flexible thin wall configuration, high vibration modes and vertical earthquake effects could not be neglected; engineering measures should be considered based on the characters of the structure for "the scourge tip phenomenon of framework top.

The model experiment of hydraulic ship lifter tower of Jinghong Hydropower Station is described from static aspect.

By dynamic test on an advanced large shaking table and three dimensional finite ele-ment calculation for shiplifter tower structure of the Three Gorge project, not only the dynam-ic characteristics of shiplifter tower structure, such as natural frequency, vibration shape anddamping ratio, but aIso the seismic responses of shiplifter tower structure to the designearthquake have been investigated.
