Abstract: On the basis of the fundamental principle of rigorous Janbu method,formulas are re-derived.Through modifying the flow of the method, the differential operation can be transformed to integral operation so as to avoid the derivative’s error. The example analysis indicates that the inherent cause of non-convergence is the assumption of rigorous Janbu method; the assumption about the line of thrust is unreasonable.

Key words: rigorous Janbu method , derivative’s error , line of thrust
