陕西八方沟尾矿库坝体变形监测与成因分析

Shaanxi Eight Side Ditch Tailings Dam Deformation Monitoring and Analysis

简单介绍了八方沟尾矿库变形观测网的布设原则及监测方法。通过对坝体的变形观测网多次观测资料的平差计算,进行了监测资料处理和精度分析,绘制观测点的变形图,分析了坝体的形变成因。监测测量成果分析说明:各级坝体水平位移处于相对稳定状态,垂直位移是因固结沉降引起的。提出了八方沟尾矿库安全运营建议。

The laying principles of Bafangshan tailings dam deformation observation network and the monitoring methods were introduced. Based on adjustment calculation of multiple observation data of the dam deformation observation network, monitoring data processing and precision analysis were carried out, and the deformation graphs for the observation points were drawn for the analysis of the dam deformation causes. The results of the monitoring and measurement showed that all levels of the horizontal displacement of the dam remained in a relatively stable state, and the vertical displacement is caused by consolidation. Safety recommendations was proposed for the operation of the Bafangshan tailings dam.
