This paper put forward the corresponding calculation method of bearing capacity to investigate the failure mode of the foundation near slope crest. Firstly，a model of bilateral failure mode for foundation near slope crest was established by considering the asymmetry of geometric size and shape of each slide block. Next，a simpli? fied analysis method for the bearing capacity of the foundation adjacent to the slope was proposed based on the upper limit theorem of limit analysis and virtual power equation，and introducing the soil strength mobilization coefficient to characterize the strength mobilization of soil far from the slope. Then，the rationality of the theoretical analysis model and calculation method was verified by the numerical calculation results of an engineering example，and the reasonable value of the soil strength mobilization coefficient was determined by comparing the results under different working conditions. The aforementioned analysis method can consider the bilateral failure mode for the foundation near slope crest and the influence of the distance between the foundation and slope crest on the bearing capacity of the foundation. Meanwhile，it can also be degenerated to that for analyzing the bearing capacity of the ground founda? tion，which can provide a certain reference for the design and calculation of road engineering in mountainous areas，and has certain theoretical and engineering application value.
