  • 由於台灣地形崎嶇陡峭,加上每年因梅雨季與颱風的侵襲,引發山崩、土石流、水災等,造成無數生命財產的損失,所以對於高風險的邊坡之監測與預警系統的開發尤為重要,本研究以物聯網架構自動監測系統對案例公路邊坡進行監測,運用自主研發之內置式傾斜儀搭配液位感測器建立無線感測系統,透過無線通信技術形成區域監測網路,再由伺服器端統一上傳監測資料至物聯網平台,達到對邊坡全自動化之即時監測目標。結合基於嚴謹力學基礎之數值分析工具對案例邊坡進行分析,選定具地錨穩定之公路邊坡場址,針對不同的地下水位及地錨強度組合對具內支撐地錨邊坡場址進行穩定性及土中變形分析,由分析結果擬訂案例邊坡之於不同時序對應不同監測物理量之客製化預警值。最終由即時監測平台整合監測系統及預警值,建立出完整的邊坡即時監測與預警系統。

    Due to the rugged and steep terrain of Taiwan, landslides and floods have caused countless losses of life and property every year during the rainy season and the strike of typhoons. Thus, the development of monitoring and early warning systems for high-risk slopes is particularly important. In this study, the automatic monitoring system based on the IoT framework is used to monitor the anchored highway slope. Use the self-developed in-place inclinometer and liquid level transducer to build a wireless sensor system module. Form the local area monitoring network with wireless communication technology, then upload the monitoring data to the cloud platform to achieve the goal of long-term automatic slope monitoring. Analyze the slope with the numerical analysis tool which is based on rigorous mechanics. While the different combination of groundwater level and anchor strength is considered, analyze the stability and the deformations of the anchored slope. With the result of the analysis, determine the warning value of the different physical quantities according to different time sequence. And finally, establish a real-time slope warning system by integrating the monitoring system and warning value on the cloud platform.
