A Study on USN Management for Tunnel Entry Slope

This research is conducted to develop the qualified data analysis system for predicting the behavior and failure of tunnel slope. The data from real-time monitoring system by CDMA communication is used to analyze the slope behavior. Tunnel slope shows different styles of behavior, because it is affected directly by temperature, rainfall and other weathering effects. In this paper, it is discussed whether the -σ management system is useful to analyze the slope or not. This analysis system is applied to a slope located at Hantijae, Pohang, which is composed of soil and weathered rocks. 10 sensors were applied there to get real-time monitoring data.
