尾矿库安全评价中坝体结构稳定性分析

Stability analysis of dam structure in safety evaluation of tailings pond

尾矿库的渗流与结构的安全、尾矿库的防洪能力在尾矿库的安全鉴定和评价中至关重要。本文首先介绍了尾矿库的概况和地形地貌。接着收集了该尾矿库的资料数据,并进行了实地考察。然后,使用ADAO软件对坝体的结构稳定性进行了计算。经过坝体结构的可靠度分析,该坝体的位移和应力状况满足规范要求。最后,得出结论该尾矿库坝体的结构是安全的,通过综合评价该尾矿库坝体的安全评级评为A级。

The safety of seepage and structure of tailings pond and the flood control capacity of tailings pond are very important in the safety appraisal and evaluation of tailings pond.Firstly,this paper introduces the general situation and landform of tailings pond.Then the data of the tailings pond are collected and field investigation is carried out.Then,the structural stability of the dam is calculated by using ADAO software.Through the reliability analysis of the dam structure,the displacement and stress of the dam meet the requirements of the code.Finally,it is concluded that the structure of the tailings pond dam is safe,and the safety rating of the tailings pond dam is grade a through comprehensive evaluation.
