通过建立国际平整度指数（IRI）数字地面模型来描述基于道路面状的IRI指标概念。在分析分形插值曲面可微的基础上,给出IRI的分形插值曲面逼近模型,由分形插值曲面模拟同一段道路路面不同时段IRI变化量的路面模型。

This paper is to explain the IRI index concept based on the road surface conditions by establishing the IRI digital road surface model.It offers IRI fractal interpolation approximation model on the basis of analyzing and researching the differentiability of fractal interpolation curved face.At last this paper gives the expressing formula and error estimation of fractal interpolation wavelet type series by IRI variation in the same road surface at different times.
