Abstract：Aimed at the present situation that the characteristics of force and deformation of the culvert un-der high embankment slope has not been systematically studied,the distribution characteristics of sur-rounding soils and deformation laws of the culvert are studied by PLAXIS finite element software com-bined with the culvert proj ect under super-high embankment loess slope at Yan'an airport.Compared the studied results with the positive buried culvert of the same working condition,some laws of force and de-formation are obtained and some problems needed to be solved in the practical proj ect are put forward.The results show that the culvert under high embankment slope is obvious in bias pressure,and incline and de-flection appear in vertical and in lateral direction.The boundary effect of slope appears when the slope ratio is 1:2 and the horizontal distance between the highest point of slope and culvert's center line is more about 10 times than the culvert's diameter under the action of culvert subjected to the bias pressure.The vertical earth pressure of culvert top under high embankment slope can be referred to earth pressure of positive buried culvert,which is designed by the filling depth of the culvert under slope,and the specific relation-ships between them remain to be further studied.
