摘要: 边坡监测受监测精度、人为误差等多方面因素的影响,导致单一监测手段无法查明边坡变形的真实情况,对边坡的稳定性状态无法做出准确判断。以湖北省十堰市某高速公路填方边坡为例,根据边坡威胁对象及变形特点,采用视频自动监测、裂缝自动监测、地表位移自动监测、深部位移自动监测多种自动监测手段,对该边坡进行综合监测,在对不同自动监测数据进行分析的基础上,采用同一时间维度对多源自动监测数据进行耦合与对比分析,并结合人工巡查情况对该边坡的稳定性进行综合评价。研究结果表明,该边坡目前整体处于较稳定状态,边坡坡顶附近存在浅表层局部变形。

Abstract: The slope monitoring results are affected by many factors such as monitoring accuracy and human data collection error. These adverse factors might result in the actual slope deformation information could not be obtained in a single monitoring method, and the slope stability state cannot therefore be accurately justified. This paper presents a case history of an expressway embankment slope in Shiyan of Hubei Province. Several different automatic monitoring methods including automatic video surveillance, automatic crack monitoring, surface displacement automatic monitoring and deep displacement automatic monitoring for the slope were used in the target slopes for the deformation characteristics. The stability of the slope was evaluated comprehensively by the coupling and comparison analysis of the monitoring data in the real time dimension based on the analysis of different automatic monitoring data, combined with artificial inspection. The results show that the entire embankment slope was in a stable state, and there is a local surficial deformation near the top of the slope.

Key words: Automatic Data Acquisition, Coupling Analysis, Stability, Comprehensive Evaluation
