Other AbstractBarrier lake is a very common geo-hazard in mountain area and open channel can be usually utilized to cope with the dammed lake emergency response,such as Tangjiashan and Xiaogangjian dammed lake after Wenchuan earthquake.But the released discharge in these cases may exceed the standard of flood control of the cities downstream,which can be still cause severe disaster to the people downstream.Indoor flume model experiments,in which such four different treatments is used as single tetrahedral solid structure(TSS),chain of TSS,single tetrahedral frame structure(TFS),and chain of TFS,are conducted to study the effect of tetrahedral structure on controlling the outburst discharge.Some conclusions can be drawn as follows:(1)when artificial tetrahedral structure is used in the tests,the peak discharge can be effectively reduced by 26.6% ~ 61.7%,ie,tetrahedral structure may have effect on controlling the peak discharge;(2)the preference order of these four structures could be:chain of TFS-chain of TSS-TFS-TSS;(3)the dam body with artificial structures remains half the original height,whereas it remains only one third without tetrahedral structures,which makes it clear that tetrahedral structures are effective in controlling downward erosion of dam body.In addition,the application of TSS and TFS is also discussed under different conditions of making process,time and cost,and if possible,linked TFS has more priorities.
