摘要
库坝区滑坡体入水激起的涌浪灾害链对水工建筑物构成安全威胁.本文对高坝大库滑坡涌浪对水工建筑物作用力相关研究成果和发展趋势进行综述,概述了国内外典型滑坡涌浪实例及其危害,基于规范推荐公式、物理模型试验和数值模拟方法对库区滑坡涌浪对大坝坝体冲击压力相关研究成果进行总结归纳,提出应关注涌浪二次冲击阶段对水工结构的影响、开展坝前涌浪回落对坝面构筑物结构产生拖曳力的相关研究.总结了涌浪对通航建筑物作用力的相关研究,分析表明,现有关于涌浪对通航建筑物作用力的研究并不完全适用于库区滑坡涌浪对高坝水工结构作用,需开展专题研究.在现状分析的基础上,对高坝大库滑坡涌·浪对水工建筑结构作用的进一步研究提出了建议与展望.
The surge disaster chain caused by the landslide entering the reservoir area poses a safety threat to hydraulic structures.This article provides a review of the research results and development trends related to the impact of landslide surges on hydraulic structures in high dams and large reservoirs.It outlines typical examples of landslide surges at home and abroad and their hazards.Based on recommended formulas,physical model experiments,and numerical simulation methods,the research results related to the impact pressure of landslide surges on dam bodies in reservoir areas are summarized.It is proposed to pay attention to the impact of the second wave impact stage on hydraulic structures,and to conduct relevant research on the drag force generated by the rebound of waves in front of the dam on the structure of the dam surface.After summarizing the relevant research on the effect of surging waves on navigation structures,the results show that the current research on the effect of surging waves on navigation structures is not fully applicable to the study of the effect of landslides and surging waves on high dam hydraulic structures in reservoir areas,and more special researches are recommended.Furthermore,suggestions and prospects have been put forward for the research on the effect of landslide surges on hydraulic building structures at high dam and large reservoir.
