PURPOSE:To make it possible to measure axial tension, shearing force and pore water pressure in the earth by one detector, by providing one load cell, which can measure the two-component forces, in one cabinet, and providing pore water pressure gages in a cabinet lid. CONSTITUTION:A detector is provided with a two-component load cell 6, which can detect the displacements of axial tension and shearing force, between a cabinet lid 3 and a bottom wall 5 of a cabinet 1. Pore water pressure gages 7 are provided in the cabinet lid 3. By using one detector, the axial tension and the shearing force are detected by the load cell. The pore water pressure at a measuring part can be measured by the pore water pressure gages provided in the detector. Therefore, the secondary stress state in the earth can be evaluated only by burying one detector in the earth. The burying work of a main body and cable can be simplified. |
