Abstract Research purposes:How to calculate soil foundation settlement simply as well as accurately is still an issue not well resolved in engineering design． The calculation program of foundation settlement was written by using the C + +and VB computer languages based on the hyperbolic curve tangent modulus theoretical basis． Then，a load test p－s curve of a railway composite foundation was calculated to verify its applicability．

Research conclusions:The calculated results show that，the hyperbolic tangent modulus method presented in this paper has high accuracy in predicting the settlement of passenger dedicated railway composite foundation，and it can forcast ahead of time before construction．This technique may be potential to calculate settlements of passenger dedicated railway composite foundation．

Key words： hyperbolic curve tangent modulus composite foundation settlement calculation p－s curve
