| Summary | To improve the limitations of rainfall-based slope warning system, a new framework that integrated the coupled hydro-mechanical analysis and wireless sensing module for field key properties is under development in Institute of Transportation, MOTC. Wireless sensing modules adopting micro-electro-mechanical system (MEMS) sensors with wireless communication components are developed and deployed in the field. This project continues the on-going research to maintain the testing sites and upgrade the modules to 4G network. A new shallow failure site located in Highway 18 has been added in this study. A new module for retaining wall inclination monitoring is deployed and a soil-structure interaction program PYWALL is adopted to predict the pre-failure deformation of the retaining wall. A cloud platform capable of data storage, display, and warning is also developed. Combining the real-time monitoring of ground hydraulic and mechanical responses and rigorous coupled hydro-mechanical analysis, a customized, time-dependent early warning system might be feasible. BENEFITS AND APPLICATIONS： 1. Develop a rigorous analytical method that integrates the failure mechanism and field material properties to predict the deep slides along roadside and provide theoretical basis of a prototype warning system. 2. Develop surface wireless sensing module for deep seated landslide warning. 3. Develop customized, time-dependent warning system and procedure to improve the limitations of current warning techniques. 4. The system potentially can be used by ministry of transportation, directorate general of highways, and Taiwan railways administration for hazard management. |
