| 摘 要： | 针对厂坝铅锌露天矿高陡边坡的特点,确定了以"GPS监测手段为主,以水准仪、裂缝仪等监测手段为辅"的监测方案,详细介绍了该方案的设计与布设.以北帮边坡1500 m台阶的监测数据为例进行了变形规律分析,并评价了北帮边坡的综合监测结果.结果表明:在监测点B03～B06的北帮边坡稳定性最差,近600 d的最大位移量为231.1 mm,存在着滑移岩体;1500 m边坡岩体的变形速率曲线显现出明显的S形,凸起段表现为由雨季降水引起的加速变形期;裂缝的累积变形阶段呈现出初期的相对稳定期、中期的变形触发期和第3阶段的稳定变形持续期;北帮中部台阶1500 m边坡的变形较其他台阶边坡显著,稳定性最差.因此,该监测系统的应用效果较好,是高陡边坡变形监测的重要方法之一.

| Abstract: | According to the characteristics of a high and steep slope in Changba Lead-zinc Open-pit Mine,a slope monitoring project was selected,which is chiefly by GPS,secondly by leveling instruments and crack instruments.Designing and construction of the monitoring system were introduced in detail.Monitoring data of the 1 500 m step of the north wall slope were taken for example to analyze the deformation law,and synthetic monitoring results of the north wall slope were evaluated.The results show that the stability... |
