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。In the condition of accidental water-losing from ship-chamber of TGP's ship-lift, the stability againstlongitudinal inclination of ship-chamber, champing loads and the variation of lifting tensile forces in steel cablesunder the clamping state, suspension state and sirnulated guide-bearing resistance state respectively were studiedon 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 sys-tem of the ship-lift can be started quickly and the clamping device may experience the maxium clamping-force. Inthe meantime, for assuring its safe operation, another reliable sfeguard measures must be set.
