摘要： 通过三峡垂直升船机1∶25物理整体模型试验，在其承船厢出现事故失水条件下，研究了夹紧状态、悬吊状态及模拟导承阻力状态下承船厢的纵倾稳定性、夹紧荷载及提升钢丝绳的张力变化。研究结果表明：当承船厢出现严重失水事故时，只要能迅速启动夹紧锁定系统，并保证夹紧装置可承受最大夹紧力，即可使承船厢不至失控，同时，为确保其安全运行，还应设置可靠的安全保护措施。

Abstract: In the condition of accidental water-losing from shipchamber of TGP's ship-lift, the stability against longitudinal inclination of ship-chamber, champing loads and the variation of lifting tensile forces in steel cables under the clamping state,suspension state and simulated guidebearing resistance state respectively were studied on the TGP's vertical comprehensive model with a 1∶25 scale.It may be found from the test that when the ship-chamber occurs a serious water-losing accident, it will not get out of control so long as the clamping-locking system of the ship-lift can be started quickly and the clamping device may experience the maxium clamping-force.In the meantime, for assuring its safe operation, another reliable sfeguard measures must be set.
