			ABSTRACT

The commonly used approaches in the analysis and design of anchor anti-slide pile are deterministic. The average values of the input parameters are usually considered and the uncertainties of the different parameters are taken into account via a global factor of safety which is essentially a “factor of ignorance.” Because of the Complexity of anchor anti-slide pile and interaction of structure and soils and rocks as well as the variability of parameters of soils and rocks, there are differences between definite analysis and practical engineering of this structure system. A reliability based approach for the analysis of anchor anti-slide pile is more rational since it enables one to consider the inherent uncertainty of each input parameter. A reliability analysis of anchor anti-slide pile is presented based on the structural mechanics calculation which is an effective method to calculate anchor anti-slid pile. Mathematical simulation is conducted using Monte Carlo method, which is not sensitive to dimension, based on calculation method. Through verifying of an engineering case, the authors work made contribution to the transition of designing method of anti-slid pile with anchored rod from definition to reliability.

Keywords: anchor pile, structural mechanics, reliability analysis, Monte Carlo simulation
