摘要
尾矿坝安全现状令人堪忧,尤其以渗流引起的坝体失稳事件屡屡出现,为了获取尾矿坝因渗流引起失稳的相关技术参数,对尾矿坝坝体稳定性进行了分析研究;在总结尾矿坝溃坝原因的基础上,分析了浸润线的影响因素并给出了计算方法,以山东玲珑尾矿坝为例,采用瑞典圆弧法和毕肖普法,对尾矿坝的整体稳定性进行计算;得到了玲珑尾矿坝相关的力学参数及计算成果,并从设计和管理两个方面讨论了尾矿坝安全稳定的防范措施;分析结果对于尾矿坝今后的设计和安全监测管理有重要的借鉴意义。
The security of tailing dams has been in an anxious situation recently.In order to get the relative technical parameters about the unstability of tailing dams coused by seepage,the impact factors of the saturation line are analyzed and a calculation method is given.Taking Linglong tailing dam in Shandong for example,Sweden circular-arc method and Bishop method are adopted to calculate the overall stability of the tailing dam,and from two aspects of design and management,the preventive measures of security and stability are discussed,so as to provide the important references for the design and safety of tailing dams in the future.
