摘要

虽然国内外对边坡破坏预警系统的监测和自动测量装置进行了很多研究,但大多数研究都是在边坡表面安装测量装置,而能够在边坡破坏和灾害发生前进行检测和预警的预警系统研究很少。本研究通过在锚杆上安装传感器进行边坡破坏模拟实验,分析边坡破坏过程中初始边坡行为特征。并对不同边坡条件(喷射混凝土边坡和天然边坡)和不同材料条件(GFRP和钢锚杆)的试验结果进行了对比和回顾。本研究可作为制定预警报警系统的基础数据,在陡坡及边坡破坏易损区发生边坡破坏前进行早期发现和预警,实现早期疏散。

Slope Behavior Analysis Using the Measurement of GFRP Underground Displacement
Although many researches related to monitoring and automatic measuring devices for early warning system during slope failure have been carried out in Korea and aboard, most of the researches have installed measuring devices on the slope surface, and there are only few researches about warning systems that can detect and warn before slope failure and disaster occurs. In this study, slope failure simulation experiment was performed by attaching sensors to rock bolts, and initial slope behavior characteristics during slope failure were analyzed. Also, the experiment results were compared and reviewed with varied slope conditions, i.e. shotcrete slope and natural slope, and varied material conditions, i.e. GFRP and steel rock bolt. This study can be used as a basic data in development of warning and alarm system for early evacuation through early detection and warning before slope failure occurs in steep slopes and slope failure vulnerable areas.
