Abstract

<p>  In a large-scale landslide, two or more slip surfaces might often occur according to activity of second order landslides. For this case, it is difficult to observe the deeper slip surface for a long term by using a conventional wired sensor so that a shallower slip surface may break the cable or the observation borehole. For the solution of the above issue, we developed the wireless sensors that combined the radio equipment with the underground displacement sensor and the pore water pressure sensor and installed those sensors in the bore holes. In this paper, we show the observation data for five years or more, and clarify the site applicability and the effectiveness of these sensors.</p>
