笛卡尔轴,直角坐标轴;
In order to calculate the intensity of general-stress in tri-axis test in geotechnical investigation, the author uses cartesian geometry principle to derivate calculation functions of common tangent points coordinates of every circle by the common tangent line. Especially, the slope tangent line is calculated directly.
