Abstract: Combining kinematically admissible three-dimensional slope failure mechanism based on the upper-bound theory of limit analysis,slope safety factor with different ratio of length to width of uniform rectangle pressure acted on slope top surface is studied systematically,and is compared thoroughly with the safety factors calculated by using FLAC software,and further with model test results,corresponding reliability of the upper-bound solutions to the three-dimensional slope stability is further di...

Key words: upper-bound solution； three-dimensional failure mechanism； finite element method； safety factor；
