Based on the indefinite method of probabilistic and statistical theory, Mathematical simulation of landslide treatment using anti-sliding pile is conducted in this paper. Through establishing the corresponding limit state equations, the reliability of anti-sliding pile is simulated using Monte Carlo Method, which is not sensitive to dimension. Through verifying of an engineering case, the authors' work made contribution not only to the transition of designing method of anti-slid pile from definition to reliability, but also to the checking of practical engineering.
