The invention relates to the technical field of railway tunnel construction and three-dimensional geological modeling, and provides a tunnel three-dimensional geological modeling and updating method and system oriented to attribute information, and the method comprises the steps: obtaining profile map data and surface elevation data, building a tunnel structure model, and building an attribute model constrained by the structure model; dividing the attribute model into a plurality of grids, and carrying out attribute assignment to obtain attribute grids; and in response to the incremental data, constructing a non-attribute grid, and according to a weighted filling principle, carrying out attribute filling according to a proportion of the attribute grid to the non-attribute grid. The method achieves the real-time control of the engineering geological conditions of the surrounding rock around the tunnel, and is suitable for the construction of a three-dimensional geological model in the whole tunnel construction
