摘　　要：随着城市的飞速发展,以传统直埋方式敷设的地下管线已经不能很好地满足现代化城市的发展需求,综合管廊的建设成为城市发展的必然趋势。为了提高综合管廊的利用效率,节省建设和运营成本,该研究在假设综合管廊是由多条垂直线和水平线组成的连续多段线基础上,以规划区内各需求点至水平线的距离加权之和最小为目标,构建了综合管廊中心线定位优化模型,得出了综合管廊中心线的平面定位。通过实例分析,验证了模型及求解程序的可行性。为综合管廊线路定位的定量研究提供了基础理论依据,并为综合管廊的合理规划提供了新思路。In recent years, with the rapid development of cities, the utility tunnel construction has become the inevitable trend of urban development because the directly buried pipelines cant meet the needs of modern urban development. To improve the utilization efficiency and to save construction and operating costs, the Line Location Theory was used to build location optimization model of the rectilinear center trajectory of utility tunnel and to obtain the location of utility tunnel, based on the assumption that the rectilinear center trajectory of utility tunnel is a continuous multi-segment line consisting of multiple vertical lines and horizontal lines, aiming at minimizing the sum of weighted distances of given points to horizontal lines in the planning zone. Furthermore, the feasibility of the model and the solution program is verified based on the analysis of an example. This work provides a theoretical basis for the quantitative study of the utility tunnel location as well as a new idea for rational planning of utility tunnel.
