摘要:
为研究贵州某待建贮灰场灰坝溃坝后对下游企业和居民区的影响，并为头顶库工程选址合理性评估及增设安全防护设施提出建议，针对该灰场灰体的不同干湿状态，选取相应的材料参数，采用离散元方法(DEM)对干灰状态进行溃坝数值模拟，同时基于水动力模型模拟雨季灰渣饱和状态溃坝情况，并分析溃坝灰流演进过程和敏感区域受灾程度。研究结果表明：湿灰对下游的影响程度相较于干灰显著提升，在极端溃决工况900 s的计算时长内，主沟最大演进距离达到1 338 m，灰流前锋流速峰值为14.4 m/s，对下游各个敏感区域造成不同程度的影响，其中居民点B受灾程度最为严重，应作为重点监控区域，对DEM和水动力模型法在溃坝量化分析中的可行性进行验证。研究结果可为灰场失事前后的早期预警和应急响应提供数据支撑。
Abstract:
In order to investigate the impact of a potential dam breach at a planned ash storage yard in Guizhou on downstream enterprises and residential areas,and to provide recommendations for the rationality assessment of the head-dam reservoirsite selection and the installation of additional safety protection facilities,corresponding material parameters were selected for the ash body in the yard under different dry-wet conditions.The discrete element method (DEM) was employed to simulate the dam breach scenario under dry ash conditions,while a hydrodynamic model was used to simulate the breach scenario under saturated ash conditions during the rainy season.The evolution process of the ash flow and the damage degree of the sensitive areas are then analyzed.The results indicate that the impact of wet ash on the downstream area is significantly more severe than that of dry ash.Within the 900 s simulation duration for the extreme breach scenario,the maximum runoutdistance along the main channel reached 1 338 m,with a peak flow front velocity of 14.4 m/s,causing varying degrees of impact on different downstream sensitive areas.Among these,Residential Area B suffered the most severe damage and should be designated as a key monitoring site.The feasibility of DEM and hydrodynamic modeling method for quantitative dam breach analysis was validated.The findings provide data support for early warning and emergency response before and after ash-storage-yard.
