| 英文摘要 | An early warning monitoring system is one of the most effective ways to reduce disasters induced by slope instabilities. The 2008 Ms 8.0 Wenchuan earthquake that occurred in Sichuan province, China, induced more than 197,000 slope failures and landslides. Othervise, there are more than 270.000 potential slope failures in Japan. To reduce vulnerability to such slope and landslide hazards, a low cost that compared to a traditional instrumentation of inclinometers and extensometer, and an effective earl warning system becomes important. For this purpose. a new monitoring method of distributed tilt sensors developed by authors, was adopted by local government of Japan and China. This is a newly simple multi-point method of monitoring landslides and slope failures, with the intention of developing an early-warning system. Surface tilt angles of a slope are monitored using this method. which incorporates a Micro Electro Mechanical Systems (MEMS) tilt sensor and a volumetric water content sensor. This system was applied to many landslides and slopes in Japan and China recently. In several case studies, including a slope failure test conducted on a natural slope using artificial heavy rainfall, the system detected distinct tilt behavior in the slope in pre-failure stages. Based on these behaviors and a conservative approach, it is proposed that a precaution for slope failure be issued at a tilting rate of 0.01 degrees/hr., and warning of slope failure issued at a rate of 0.1 degrees/hr. (Uchimura et al. 2015). The development of this system can occur at a significantly reduced cost compared with curmnt and comparable monitoring methods. |
