    摘要:

    水库两岸的岩石块等滑坡体滑落入水后,引起的滑坡涌浪常常会造成各种安全生产事故,严重威胁航行安全和国民经济。为揭示涌浪传播至船舶附近时的爬高特性,本文以三峡库区为研究对象,结合滑坡涌浪进行物理模型试验,制作概化滑坡体,利用浪高仪分别采集河道中两个船模表面附近的四组涌浪数据。试验结果表明,涌浪受船模、河岸等障碍物阻拦后的回流波与初始波叠加后,在船模表面附近的部分观测点产生了二次、三次波峰,会对行船稳定及安全造成二次危害。总结出在不同位置的船舶附近各观测点的涌浪爬高特性,根据其最大波峰、波谷等数据,为船舶航行安全预防性措施提供理论支持。

    Abstract:

    After landslide bodies such as rock blocks on both sides of the reservoir slide into the water, the landslide surge often caused various safety production accidents and seriously threaten navigation safety and the national economy. In order to reveal the climbing characteristics of the swell when it spreads to the vicinity of the ship, the Three Gorges Reservoir area as the research object was taken, the physical model test with landslide body was established for landslide surge, and the wave height meter was used to separately collect four sets data of two ship models of surge near the surface. The results show that after the surge wave is blocked by the ship model, the river bank and other obstacles, the return wave and the initial wave are superimposed, and the second and third wave peaks are generated at some observation points near the surface of the ship model, which will cause secondary hazard for the stability and safety of the ship. The characteristics of surge climbing was summarized by observation points near the ships in different positions. Based on the data of maximum peak and trough, the theoretical support is given for the preventive measures of navigation safety.
