【摘要】：為了提出適用于堰塞湖潰決模擬仿真的方法,在系統(tǒng)梳理FREAD潰壩洪水分析體系DWOPER、DAMBRK、BREACH和FLDWAV模型的基礎(chǔ)上,對各模型的基本原理、適用條件及優(yōu)缺點(diǎn)進(jìn)行了匯總�；诟髂Ｐ偷墓δ芴攸c(diǎn),聯(lián)合使用BREACH潰壩計(jì)算模型及FLDWAV洪水演進(jìn)模型反演了尼泊爾遜克西(Sunkoshi)堰塞壩的潰決過程。結(jié)果表明:遜克西堰塞壩潰決過程歷時(shí)68 min達(dá)到潰決洪峰流量1 794 m3/s,考慮到支流入流的情況,潰決洪峰歷時(shí)154 min演進(jìn)至下游37.9 km處的庫帕瓦加特(Pachuwarghat)水文站,計(jì)算流量結(jié)果與該水文站實(shí)測數(shù)據(jù)較為一致,從而驗(yàn)證了聯(lián)合使用BREACH和FLDWAV模型進(jìn)行堰塞湖潰決計(jì)算的合理性和可行性。研究成果可以為制定類似堰塞湖潰決的應(yīng)急處置方案提供參考。
[Abstract]:In order to put forward a method suitable for simulation of dammed lake outburst, the basic principles of each model are analyzed on the basis of systematically combing the FREAD dam-break flood analysis system (DWOPERERA) DAMBRKU BREACH and FLDWAV model. The applicable conditions, advantages and disadvantages are summarized. Based on the functional characteristics of each model, Combined use of BREACH dam break calculation model and FLDWAV flood routing model, the collapse process of Sunkoshi Weir dam in Nepal is inversed. The results show that the collapse process of Sunkoshi Weir dam in Sunkoshi, Nepal, takes 68 min to reach Hong Feng's discharge of 1 794 m3 / s. In the case of a tributary inflow, At the Kupawagat Pachuwarghat Hydrological Station, which lasted from 154 min to 37.9 km downstream, the calculated flow rate is in good agreement with the measured data of the hydrologic station. Therefore, the rationality and feasibility of the combined use of BREACH and FLDWAV models for the calculation of lake outburst are verified, and the research results can be used as a reference for the formulation of emergency treatment schemes similar to those for the dammed lake outburst.
