测斜仪在山体滑坡监测中的应用与分析

Application and Analysis of Inclinometer in Monitoring Landslide Deformation

简要介绍测斜仪的构造、工作原理以及测斜仪产生误差的主要因素。以化乐山体滑坡监测工程项目为例,说明测斜技术在地基监测中的实际应用情况。通过对山体不同分布位置的五个关键监测点以每半个月为周期的动态数据监测并进行汇总,对记录数据处理得到各个监测点随时间而变化的深度-位移曲线,从而达到比较清晰地了解山体短时间内的滑坡变形情况。通过深度-位移曲线的变化规律进行地质分析,为山体滑坡的治理提供重要依据与客观建议。

First, this paper briefly introduces construction and principle of the inclinometer, analyzes the main factors which cause inclinometer produce deviation. Then, take landslide monitoring project in Huale as an example explain application of inclinometer in monitoring landslide project. Though monitoring the five key points distributed in different locations and gathering all monitoring- data half month as a period, handle monitoring-data to get depth-displacement bight followed with time of each monitor point so that we can comparatively and clearly master situation of landslides in each interval short time. Finally, we can provide important basis and objective advice for administer landslide through analyze the change regulation of depth-displacement bight.
