| As for the ground anchors constructed on the slope disaster prevention work, it is very important to grasp residual tensile force of the tendon, and to understand the long-term tendency in operation and maintenance for the structure.This time, the new method was developed to measure the residual tensile force of existing ground anchors by joint research with PWRI and eight private companies. The developed system is composed of three elemental technologies as "Load cell which can exchange", "Special treatment device for load cell installation", and "Accumulation system for measurement data ".This paper shows the outline of this new method. |
