中文摘要红石岩堰塞湖是2014-08-03鲁甸地震诱发形成的大型堰塞湖,由红石岩崩塌堵断牛栏江形成。红石岩堰塞坝坝高约96 m,堆积体总方量约1 200×10~4m~3,湖区满库库容为2.6×10~8m~3。从红石岩堰塞湖形成的背景条件,以及堰塞湖对坝址所在流域构成的潜在灾害链效应,评估堰塞湖的溃决危险程度。同时根据可能的溃决形式分析,采用1/3和1/2溃决模式对堰塞湖溃坝洪水估算,得到两种工况条件下的峰值流量分别为:Q_p≈(1.3~1.5)×10~4m~3/s和Q_p≈(2.2~2.8)×10~4m~3/s,远超过坝址处500 a一遇的牛栏江暴雨洪水,并在此基础上对下游演进过程的洪水进行估算。认为红石岩堰塞湖在后期整治中仍存在库岸稳定、堰塞坝稳定和鱼类生态破坏等问题,应引起关注。 
英文摘要Hongshiyan is a huge dammed lake induced by Ludian Earthquake on August 3,2014,and formed by a large landslide blocking the Niulanjiang River. Hongshiyan dam is about 96m in height and 1 200 × 104 m3 in volume, with a capacity of 2.6×108 m3 in the reservoir. This article reveals the forming conditions of Hongshiyan dam in topography,geology and water source,analyses the potential chain effects impacted on the nearby area,and assesses the risk of dam break. Hongshiyan dam is distinguished as a high level of failure risk by using a method of Dimensionless Blockage Index,and outburst floods under different breach mode are estimated. By calculating,the peak discharge are Qp≈( 1.3~1.5)×104 m3/s in 1/3 height of dam and Qp≈( 2.2~2.8)×104 m3/s in 1/2 height,which are much larger than the 500 - year flood in section. Finally,risk management for Hongshiyan dammed lake is summarized and analyzed,problems of the stability of Hongshiyan dam and banks aside the lake,
and the ecological destruction of fish are proposed.
