Experimental Investigation and Design of Artificial Structures Controlling Dam-Break Floods

摘要

摘要:为检验人工结构体对堰塞湖溃决洪峰流量的调控作用,进行了室内水槽模型试验.试验主要针对四面体实体结构、四面体实体结构串、四面体实心框架结构和四面体实心框架结构串.试验结果表明:抛投人工结构体对堰塞湖溃决后期洪峰流量的控制作用非常显著,与未抛投人工结构体相比,4组抛投人工结构体的洪峰流量减小26.6%~61.7%;人工结构体的优选型式依次为四面体实心框架结构串、四面体实体结构串、四面体实心框架结构和四面体实体结构;增大人工结构体的容重能改善堰塞湖溃决洪峰流量的调控效果.

Abstract:In order to verify the control effect of different artificial structures in dealing with barrier dam-break floods, flume model tests were conducted in lab on tetrahedral entity structure (TES), tetrahedral entity structure group (TESG), tetrahedral frame structure (TFS) and tetrahedral frame structure group (TFSG). The research results show that throwing artificial structures has an important effect on the control of barrier dam-break floods, and compared with no throwing artificial structures, throwing artificial structures can effectively reduce peak break-out floods by 26.6% to 61.7%. Different artificial structures have different control effects, and optimal structures are in sequence TFSG, TESG, TFS and TES. In addition, increasing unit weight of artificial structures can improve the control effect.
