摘要
以库区滑坡资料分析为前提,采用物理模型综合影响因素的正交试验,定性和定量地对山区河道型水库岩体滑坡涌浪的传播特性进行研究,并以滑坡涌浪水域定速航行船舶为对象,研究该水域航行船舶复杂的非线性运动特性,探讨船舶的倾覆及沉没条件.研究表明:滑坡体的宽厚比越大,产生滑坡涌浪首浪高度越大,波能量越大,对船舶的横摇及纵摇的影响越显著.在实际工程中,应该做好滑坡体的排水处理,分段治理和分级削坡,调整船舶在滑坡涌浪水域的航行状态.研究结果可为防灾减灾工作提供科学依据,为船舶在滑坡涌浪水域安全航行提供一定的理论基础及技术保障.
Based on data of landslide and orthogonal test design,propagation characteristics of landslide surge arestudied qualitatively and quantitatively.Conditions of capsizing and submergence of a ship with constant speed are explored.It is shown that with increase of the ratio of width to thickness of the landslide,the height of the first landslide-generated wave and the energy of the landslide-generated wave will be increased,which may have significant influence on the roll and pitch of the ship.The research will provide the scientific basis of disaster prevention and mitigation,and technical support for safe navigation of ships in the landslide-generated wave.
