The Circle of Mohr is widely used in soil mechanics, from which the cohesive stress c and the angle of internal friction φ is usually gained by using diagrammatical method, where the precision is relativelg low and the result is obviously influenced by artificial factor. In the paper an optimal fitting method to overcome such a shortcoming is introduced. Now the c? φ value of the Circle of Mohr can be computed with high precision and the results is more reliable, where the calculation procedure is programmable and the result can be easily expressed in the form of the computer graphics.
