Abstract:
1. An instrument for measuring torsion moment of a single-pole cylindrical foundation, comprising: a force-applying means that applies horizontal force to structures protruding from the ground; a tension means that is connected with the force-applying means to apply tensile force to the structures; a measuring unit that is disposed inside the structures to measure strain per depth and portion due to force applied from the tension means; a controller that analyzes moment per depth of the structures from horizontal force measured by the measuring unit; a load gauge that measures applied load at the ioint between the top of the structures and the tension means, wherein the load gauge checks the load and controls the magnitude and the rate at which the load is applied from the force-applying means; and an automatic clinometer that measures horizontal behavior per depth, in the lower portion of the structures; wherein the controller includes: a force-applying means control module that controls force applied to the force-applying means; an analyzing module that analyzes moment and ground behavior from the values measured by the strain gauge and the automatic clinometer; and a storage that stores the moment and horizontal displacement when the structures are designed.
