Abstract A new stability analysis method——equal arc method(EAM) is presented. Based on this method，the soil upon the most dangerious slip plane is divided into a number of vertical soil-slices whose lengths of arc are equal. The safety factor of stability is a function of geotechnical parameters，retaining and protecting parameters，distribution of ground load，state of foundation pit excavation and circle-center-coordinates of the most dangerious slip plane. The visual software is developed and an engineering example is introduced.

Key words： equal arc method(EAM) foundation pit soil nailing wall safety factor of stability
