A self-adaptive smoothing modeling method for tunnel nodes based on centerline topology relationship
The three-dimensional roadway structure in underground space is complex and the model data is huge.In order to solve the problem of fine expression of roadway at special locations such as intersections,this study proposed a self-adaptive smoothing modeling method for tunnel nodes based on centerline topology relationship.Based on the roadway centerline data,the method adaptively discriminates the topological relationship between the child nodes under the root node to distinguish different types of roadway.A semi-arch surface was designed to build corresponding model components and the method of component splices was used to realize fine and smooth modeling.Finally,by verifying the data of a certain section of roadway,a complete roadway model smoothly connected by various intersections such as three-way and four-way intersections was established,which provides an effective solution for the accurate modeling of complex roadway in underground space.
