南迴鐵路段「土石流徵兆預警」偵測系統實驗 Experiment of the “Early Warning Solution of Landslides” Detection System in the TRA South-Link Line
進行系統設定。

為期透過先進偵測設備及數據分析技術,藉以掌握邊坡狀況,進一步實施防範作為,以維護鐵路行車安全。前於105年12月初至南迴鐵路(台東路段)辦理現勘後,鐵路改建工程局再次會同本局及臺灣鐵路管理局,於3月1日與NEC公司進行南迴線的內獅十號橋與十一號橋間處邊坡,及達信二號橋南方邊坡兩處之現勘,經實地勘查及評估討論後,決定次日於達信二號橋南方邊坡裝設「土石流徵兆預警」偵測系統實驗設備。
考量現地附近未具有可使用之電源及光纖網路訊號,因此採用獨立電源及訊號箱收集各項數據,同時NEC並蒐集實驗地點之土壤帶回日本總實驗室進行其他各項實驗及數據分析工作。
截至四月底,本次實驗數據已收集一個半月,目前遇降雨時皆有偵測到穩定係數下降資訊,另經NEC公司日本總實驗室依採樣土壤分析後得出安全標準,將於颱風季節時實際驗證本套系統於臺灣山區之成效,以供鐵工局、臺鐵局及本局作為後續系統應用之參考。

With advance detection equipment and data analysis technology to grasp the slope conditions, further preventive actions can be implemented to maintain the safety of railway traffic. After the inspection in early December, 2016, the RRB once again invited BOHSR, TRA and NEC Taiwan Ltd. to South-link Line inspection on Mar. 1 at the slope between Neishi No.10 Bridge and Neishi No.11 Bridge and two sites on the south side of the Dashin No.2 Bridge. After onsite inspection and assessment discussions, it was decided to install the experimental equipment for the detection system of “Early Warning Solution of Landslides” on the next day on the south slope of Dashin No.2 Bridge.
Considering the use of power and fiber optic network signals in the vicinity of the site, independent power and signal box were utilized to collect the data. Simultaneously, NEC will collect the soil sample at the experimental site back to Japan's laboratory for other experimental and data analysis.
As of the end of April, the experimental data has been collected for a month and a half. At present, when the rain is detected, the stability coefficient is detected of descending. The safety standard was obtained via soil analysis by the general laboratory of NEC Corporation in Japan, and the effectiveness of the system will be verified in the mountainous areas of Taiwan during typhoon season as a reference for future applications of follow-up systems in RRB, TRA and BOHSR.
