Paper Abstract

Urban Underground Pipeline System has grown up to diversity and complex networks; moreover, they have the characteristics such as invisibility, magnanimity and continuous variation. It is necessary for accelerating development of city to establish integrative model of urban pipeline-road-stratum with the techniques of Digital Underground Space and Engineering (DUSE). The key method of some spatial analysis are presented in the present model, it includes integrative break surface analysis, horizontal net distance analysis and cross vertical net distance analysis in any of the given section; especially, DUSE takes out the three dimensional distance analysis or interference judgment between pipelines. Nowadays, the general method which distinguishes the state of interference in multi-manipulator system simplifies shaft into line-segments, then calculates the distance between two line-segments or the intersected position without taking the shape of shaft into consideration. In DUSE, the state of interference in pipelines is computed by Boolean operation; if two pipelines haven't intersection, a series of algorithms based on the theory of analytic geometry is put forward to calculate 3D distance between circular pipelines, quadrate pipelines or their combination.
