Three-dimension design method based on cable engineering information model

The invention relates to a three-dimension design method based on a cable engineering information model. The three-dimension design method comprises the following steps: 1), according to main problems existing in city power cable and channel management at the present stage and defects of the conventional two-dimension design, which exist in actual engineering, determining an application field of the cable engineering information model; 2), determining demands in the three stages of cable engineering building, design and drawing and obtaining the achieving purpose of the cable engineering information model; 3), building the cable engineering information model by using a three-dimension design platform and according to a standard model base and regional digital model base; 4), carrying out three-dimension design on cable engineering according to the cable engineering information model and by combining cable structure parameters, a cable laying method and cable running parameters, and finally, obtaining a three-dimensional cable engineering designing scheme. Compared with the prior art, the three-dimension design method provided by the invention has the advantages of being intuitive and accurate, and advanced in platform and the like.
