The urban rail transit tunnel has many forms, such as single hole single line, single hole double line, parallel and non - parallel, intersection and separation, etc., The modeling is more complicated, the existing 3D modeling method of simple tunnel cannot meet this complexity requirement. According to the actual situation of urban rail transit tunnel, the paper defines the data structure of tunnel modeling, and puts forward the three-dimensional coordinate calculation method of different tunnel forms. According to the actual situation of urban rail transit tunnel, the paper defines the data structure of tunnel modeling, puts forward three-dimensional coordinate calculation method of different tunnel form, and realizes the 3d rapid modeling of urban rail transit tunnel, which meets the multiple modeling requirements of the tunnel.
