【Abstract】：According tothe specialflow characteristicsofflood storage and detentionareaandthedrainage requirements of urban roads，a pipe soil water solid coupling numerical model is established，and the effcts of incoming water level，velocityand direction on culvert structure andsubgrade stabilityare considered.The results show thatthe firstinflowmainlyaffects thestabilityoftheintake，andtheincreaseofunitwidthflow infrontof the culvertleads to the maximum stress concentrationand deformation；The efectof incoming water leveland velocityonthe improvement of pipeculvert discharge capacity is limited，and the backwater in front of the culvert and subgrade scouring are easy to be caused when the hydraulic calculation is unreasonable；Oblique incoming water will reduce the drainage efficiency of pipe culverts and aggravate bank scouring.
