| 摘 要： | 从尾矿坝溃坝概率计算、溃坝砂流下游演进模拟、溃坝事故造成的伤亡人数估算、溃坝生命损失可接受风险标准的制定及降低风险的最优安全投入几个方面全面系统地对尾矿坝溃坝生命损失风险控制进行了研究.建立了尾矿坝坡失稳破坏的功能函数及我国尾矿坝溃坝个人生命损失可接受风险标准.以某一尾矿坝为例,进行了实例分析.通过对挽救生命损失的最佳安全投入进行计算,得到最优安全投入为390万人民币,并对比美国和我国现行的工伤死亡赔偿标准,建议我国相关部门提高工伤死亡赔偿标准.

| Abstract: | The failure probability of tailings dam， evolution simulation of sand flow downstream of dam break， the loss of life ，the life loss risk acceptable criteria of the tailings dam break， and the best safety investment to save lives were studied. The tailings dam slope failure function and the personal life acceptable risk criteria of tailings dam break were established. Taking a tailings dam as an example， a case study was carried out. The optimal safety investment for life saving was calculated to be 3.9 million RMB. Compared the standard of the United States with China′s current industrial injury death compensation， it is suggested that the relevant departments of our country should improve the compensation standard for work-related injuries. |
