Project Overview：
The purpose of this research and development is to conduct analysis on shallow landslides that damage slopes along highways through an analytical method, and also researches and develops a matching wireless sensing soil layer response module, to develop an early warning model different from the existing empirical method using rainfall monitoring as an indicator to enhance the accuracy and timelyness of early warnings. The module design uses the micro-electromechanical sensing components of various consumer electronic products to monitor the real-time data of surface dip angles, surface displacement and stratified water content in the soil, and combines these with wireless communication technology to write control firmware, to construct the distributed sensing network, which is an easy-to-install, low-cost, disposable monitoring module. The current research and development outcomes can be used for monitoring shallow landslides on slopes along highways.
Research outcomes：
(1)Completed the theoretical analysis of hydrodynamic coupling slope stability caused by infiltration of infinite slopes resulting in shallow slides, and established wireless monitoring module integration test and data system architecture.
(2)Designed a power-saving control mode, programmed power-saving control and data collection transmission firmware, for which not only the local site does not need to set up a server, but which also alleviates the longstanding dilemma of insufficient power for the facilities on local sites.
(3)Set up two highway soil side slope shallow collapse wireless sensing network module test sites (Xihu and Jiaxian site) to conduct long term monitoring of local sites, data interpretation and model adjustmens and applications.
Promotion of Outcomes and Benefits ：
(1)The current signal transmission module used must have a certain power, but on rainy days the transmission distance is reduced. In the future, a suitable transmission network or integrated high-power wireless transmission components will be used to deploy the equipment and expand the system.
(2)The current research and development outcomes are applicable to the monitoring of shallow soil side slope collapses. In the future, we hope to conduct further research into side slope deep layer damage theory and develop simple monitoring software and hardware modules for applicable for deep layer damage.
(3)In November 2017, this Institute planned and managed the "2017 Road and Bridge Disaster Prevention Technology Seminar", and invited the Freeway Bureau, Directorate General of Highways, Taiwan Railways Administration, Bureau of High Speed Rail and local governments to discuss the research outcomes, to promote the application of outcomes and to discuss directions for future improvement.
