基于脆弱性曲线的寿溪河流域村镇建筑洪灾风险评估
Flood Risk Assessment of Rural Buildings in Shouxihe Basin Based on Vulnerability Curve
摘要
Abstract
Rural buildings in Shouxihe Basin(SXHB)were taken as studied objects.Based on MIKE FLOOD coupled hydrodynamic model,the temporal and spatial distribution characteristics of inundation in SXHB were simulated and analyzed.Then,the vulnerability curve of rural buildings on flood risk was established from the theory of structural static mechanics and the empirical equation of flood load.Finally,the flood risk assessment of rural buildings in SXHB was conducted based on the results of hydrodynamic model and vulnerability curve.It is found that the inundated area is long,narrow,and with a large value of flow velocity.The buildings are majorly at low or middle risk in low return periods,whereas in high return periods buildings at high or extremely high risk locate nearby the dam-break,in the major inundated area,and at Heba Village.Flow velocity is considered as a parameter in the vulnerability curve which reflects the damage degree of rural buildings.关键词
