Abstract

 Ground anchoring is one method for maintaining the stability of slope. When under construction, the tension of the anchor is usually managed by a load meter. At that time, the stability of slope is evaluated by checking the tension of ground anchor.
 However, there are cases where the measurements of a loadcell do not show a constant value even on stable ground. In addition, it is difficult to set a loadcell to a working anchor. Appropriate monitoring methods have not been established to date as well. In this paper, we have analyzed the characteristics of the measured loadcell values, looking at loadcell data collected on multiple slopes. Moreover, we have developed two new technologies. One is the technology to confirm functions of the loadcell. Another is a method for attaching loadcell to working anchors. Finally, we propose a monitoring method for the residual tensile load.
