摘要/Abstract

摘要： 在对比地表集中荷载模型和二维有限载荷模型的基础上, 结合营口台SQ-70模拟水平摆倾斜仪2009~2016年异常变化时段受矿山开采影响的实例, 采用二维有限不规则荷载模型定量计算了矿山开采的不同阶段对石英摆倾斜量的影响程度。结果表明: 营口倾斜观测受周边矿山开采影响严重; 2009年以后矿山开采量引起营口地区地表倾斜的理论值与实际观测值基本相符, 该时段数据破年变异常为矿山开采影响的可能性较大; 2013年以后营口石英摆观测值与矿山开采引起地表倾斜的理论值相差较大, 因此2013年后的数据异常变化不完全是矿山开采引起, 可能是地壳倾斜变化的实际反映。

Abstract: Based on the comparison between the surface centralized load model and the three-dimensional finite load model, An example of mining impact during the period of abnormal change from 2009 to 2016 by using Yingkou SQ-70 analog horizontal pendulum tilt instrument, The theoretical value of the influence of different stages of mine mining on the tilt of quartz pendulum is calculated quantitatively by using the 2-D cable irregular load model. The results show that: In 2009, this period of time is abnormal for mining as the theoretical value; after 2013, removal of rainfall northerly influence more than the theoretical value of the calculation results, therefore, the abnormal changes after 2013 can not be attributed to the load changes caused by mining, This is also the actual reflection of changes in the inclination of the earth’s crust, Quantitative calculation of the effect of load on the tilt observation of quartz pendulum, It can play an auxiliary role in the abnormal analysis and determination of tilt observation data.
