摘要:
为了研究钻孔测斜仪在滑坡监测过程中如何有效节约监测时间及劳动成本,提高工作效率,通过使用RQBF-698B型钻孔测斜仪对贵州省化乐煤矿三井区的滑坡带监测中,总结出一种提高钻孔测斜仪监测效率的方法。测斜仪的原理是一个力平衡式的伺服系统,通过传感器多次测量地下水平位移,从而判断地下是否存在滑动。在监测过程中,每次需要大量时间测量相互垂直方向的2组数据,然后通过矢量计算得出滑动方向与位移。如果能对滑坡滑动方向的预判,在安装测斜管时有目的性的设置主方向,根据测斜仪原理,每次监测只需测量该主方向的滑动数据就能获得有效准确的监测结果。本次的钻孔测斜仪的监测结果分析得到的滑坡体滑动面及滑动趋势,与钻探、坑探结果一致,取得了较好的监测效果。研究认为在预知滑动方向的前提下,可以有方向性的安装测斜管,这样可以在获得准确的监测结果的同时,提高了监测的工作效率,缩短监测时间。这样的方法适用于滑坡体滑动方向可以准确预判的情况。如果滑坡滑动方向预判不准确,得到的监测结果将与事实相差甚远。
Abstract:
This paper aims to study how to reduce the time to monitoring,enhance the work efficiency in the process of landslide monitoring with the borehole inclinometer.In the monitoring process,the paper concludes a method which can enhance the working efficiency of monitoring.The principle of inclinometer is a servo system of force balance type and it measures the horizontal displacement many times through the sensor in order to judge the activity of landslide.In the process of monitoring,it often takes much time to measure and get two groups data in two perpendicular directions,then the sliding direction and displacement can be got through the vector calculation.If the sliding direction of landslide could be predicted and the sliding direction sets as the main direction when install the inclinometer pipe.Based on the principle of inclinometer,each monitoring only need to measure the main direction of the sliding data.This also can get effective and accurate monitoring results.The monitoring results of borehole inclinometer consistent with drilling,pitting results,which shows good monitoring effect.The study shows,on the premise of predicting sliding direction,it can obtain accurate monitoring results,at the same time,improve the efficiency of the monitoring as the inclinometer pipe set directive.This method is suitable for the landslide sliding direction with accurate predictions.If landslide sliding direction anticipation is not accurate,the monitoring results will be far from the truth.
