摘要:
为了对天然气长输管道等设施穿越尾矿库下游形成的“头顶库”风险进行量化分析，基于假定和边界条件构建了尾矿库溃坝风险分析模型，并通过引入计算公式构建了尾矿库溃坝风险量化分析模型，提取了冲击波超压和爆破地震烈度法计算公式来量化分析管道爆炸对尾矿库影响效应。以福建龙岩某尾矿库“头顶库”为例，研究了该尾矿库溃坝后冲击力是否会造成管道断裂；模拟了爆炸对人员影响的范围；进而分析了管道完全破裂后爆炸造成的冲击波和爆炸振动对尾矿库的影响。研究结果表明：在500 a一遇的洪水条件下，尾矿库溃坝下泄的泥砂流对该穿越管道造成的冲击力不会造成管道断裂；管道泄漏10 min的爆炸情形产生的爆炸冲击波对尾矿库坝体结构没有影响，产生的等效爆炸地震烈度大于尾矿库的抗震设防烈度6度。可为同类实例提供工程理论方法。
Abstract:
In order to quantitatively analyze the risk of overhead tailings pond, where there is a dangerous longdistance natural gas pipeline crossing through the downstream of tailings pond, a risk analysis model of tailings dam break was constructed based on the assumptions and boundary conditions, and a risk quantitative analysis model of tailings dam break was established by introducing into the calculation formulas. According to the research contents, the calculation formulas of shock wave overpressure and blasting seismic intensity method were extracted to quantitatively analyze the effect of pipeline explosion on the tailings pond. Taking a overhead tailings pond in Longyan, Fujian Province as an example, the numerical simulation was carried out by using the risk analysis model of tailings dam break, and whether the impact force of tailings dam break caused the pipeline fracture was studied. Based on the explosion model of complete fracture of pipeline, the influence range of explosion on personnel was firstly simulated, and the effect of blast wave and explosion vibration caused by the pipeline explosion on the tailings pond was analyzed. At the same time, it provides the engineering theory and method for the similar examples.
