To analyze the influence of vehicle load, vertical earth pressure, static active earth pressure and water buoyancy on the stress of the whole structure of integrated pipe gallery intersection under different buried depth conditions, a 3 D finite element model of the intersection is established and analyzed. The analysis results show that the maximum bending moment of the roof plates, bottom plates and sidewall plates of the intersection increases gradually with the increase of the depth of the intersection, but the increase is small, while the maximum bending moment of the intersection frame increases greatly.
