碩士 === 明新科技大學 === 土木工程與環境資源管理系碩士班 === 103 === Because of the rapid growth of the national economy, transportation increasingly frequent, so that the carrying capacity in the hillside could be supercharged. And the geographical environment in Taiwan belonging to the island climate, the structure is affected by high temperature and humidity, coupled with the impact of acid rain, air pollution, and natural hazards. The chances of damage to the hillside will be increased. To maintain the safety and operation, it is an urgent task to perform the security monitoring and evaluation for the hillside, and to develop further maintenance and reinforcement. After the landslide hazard range of 3.1 km in the third highway, causing enormous shock in the traffic conservation units. Suppose bridges or hillside in the railway to happen similar incidents, it will cause great damage to the track and the safety of people and vehicles. It is a very important issue how to perform the safety assessment ensure driving safe in the railway. Therefore, the purpose of this study is to establish a real-time monitoring mechanism for the railway safety. A railway safety monitoring real-time warning system consist of tilt meters, displacement meters and digital cameras via a 3G network transmission had been well developed in this work. The wall-body tiltmeter is used to measure the tilt amount of track structure. Moreover, a cable-displacement meter used to detect the amount of displacement, and the railway surrounding circumstances can be watch by CCD digital cameras. All monitoring data (including live video) are transmited into the system via 3G internet transmission. The established instant alert system combining with automated real-time alert notification function, automatically judgement and storage according to the monitoring data, and immediately start warning lights when monitoring data exceeds the alert value; and provide text message notification via mobile phone. This planned monitoring and warning system had been installed at the Xinfeng K97 +600 ~ K98 +500 section in the western railway line of Taiwan Railways Administration. The field monitoring results show that the system can effectively monitor whether abnormal change occurred in the hillside of the track structure. While a landslide event occurred surrounding the railway track, it did help maintenance unit to taking emergency responses in a timely manner to ensure the safety of passenger lives and trains.
