城市道路管线综合横断面规划的多目标数学模型

Multi-objective model of the pipelines comprehensive planning under the urban road cross-section

明确管线综合横断面规划的基本要点后,根据管线综合横断面规划的期望目标和原则,借助多目标规划法的通用原理,建立与道路中心线、相邻管线、树木根茎距离最远,同时管线用地最省为目标的管线综合横断面规划数学模型.某工程实例的应用效果表明:该模型可在满足多种约束条件的情况下,给出道路横断面内各种管线位置的定量化最优解.

An introduction to the basic elements of pipelines comprehensive planning under the urban road cross-section （PCPuURCS） was briefly done in this paper.A multi-objective planning model which aims not only at lengthening the distances from each pipeline to the urban road centerline,as well as to the adjacent pipelines and tree roots,but also at reducing the land occupation of all of the pipelines under urban road cross-section,was established based on the generic principles of PCPuURCS.With a engineering case,it is suggested that the quantitative optimal solutions of PCPuURCS can be located while variations of constraints can be satisfied at the same time through the multi-objective planning model obtained.
