PRINCIPAL STRESS CALCULATION PROGRAM, AND PRINCIPAL STRESS CALCULATION METHOD
To provide a principal stress calculation program capable of solving problems of conventional arts, that is, relatively easily obtaining principal stress of anisotropic rock mass from a result of an original position test, and a principal stress calculation method using the program.SOLUTION: A principal stress calculation program is a program for causing a computer to execute a function for obtaining a maximum principal stress σ1∞, a minimum principal stress σ2∞, and a working angle α of principal stress of rock mass, based on a first deformation coefficient E1, a second deformation coefficient E2 and an initial loading pressure p0 for N times, which are obtained by performing a loading test, in which a wall surface of a borehole provided in anisotropic rock mass is pressurized by a uniform displacement loading method, while changing a loading direction. The principal stress calculation program comprises a function that causes a computer to execute condition value acquisition processing, working angle setting processing, provisional principal stress calculation processing, sensitivity coefficient calculation processing, difference sum square calculation processing, working angle determination processing, and principal stress determination processing.SELECTED DRAWING: Figure 7
