Abstract：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 can't 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.
