Evaluation methods for the "deformation characteristics and stability" of rock mass structures: deformation anisotropy and simple shear.
Essential evaluations in pre-construction surveys, seismic design, and maintenance management of rock mass structures.
【Deformation Anisotropy】 "Method for identifying the orthotropic elastic properties of rock masses through uniaxial testing" - Can identify three principal axes + 9 parameters (not possible with conventional techniques) - Significantly fewer tests required (3 cylindrical specimens) - Applicable to prismatic specimens as well - Low cost, high precision 【Simple Shear】 "Simple shear testing of rock prismatic specimens using torsion" - The only testing method available in the country - Clarifies the deformation characteristics of rocks during earthquakes - Obtains data necessary for seismic design - Evaluation of repeated "shear" - Traffic loads from vehicles and trains - Foundations of offshore wind power affected by wave action
