Development of Landslide Early Warning Using the Self-PotentialMethod : In-situ Observation

通过本研究项目，取得的科学成果如下：（1）开发一个紧凑的数据采集系统，该系统具有多通道和太阳能电池，用于现场滑坡的自然电位观测，（2）开发自然电位层析成像和降噪技术，以可视化地下水状况，（3）在德岛的西岩川建立一个实用基地，日本将监测现场斜坡的自然电位。这些成果为滑坡过程的水文-岩土-电磁耦合研究提供了新的发现，积累了现场观测资料。在国内外会议上发表了10篇科学论文（4篇带综述）和34篇科学报告。

Through this research project, the scientific achievements are as follows: (1) Development of a compact data acquisition system with multi channels and solar battery for in-situ landslide observation of self-potential, (2) Development of self-potential tomography and noise reduction to visualize underground water condition, and (3) Installation of a practical base at Nishi-Ikawa, Tokushima, Japan to monitor self-potential at an in-situ slope. These achievements provide the new findings on hydrological-geotechnical-electromagnetic coupling for landslide processes and accumulation of the in-situ observation data. And they have been reported in 10 scientific papers (4 papers with review) and 34 scientific presentations at international and domestic meetings.
