| Outline of Final Research Achievements |
Slope structure health monitoring system for preventive maintenance of expressway which has the significant role as transportation infrastructure was developed. This system has three features for maintaining safety of slope structures along expressways. One is the feature to monitor shallow and deep landslide risks real-timely. Another is the feature to evaluate structure health conditions of a slope by a ground anchor method.
The other is the feature to evaluate an effect of drainage on an embankment. The monitoring device that is set up on a slope has function for building wireless communication network automatically by small battery and the data are sent to a Web server through 3G wireless module.
