摘　　要：在地下管廊的普遍建设中,因年代久远,管廊的原有设计稍显落后,因此,提出基于AHP法的城市地下缆线型综合管廊标准断面选型优化。在原有管廊的设计规划上,贴合时代技术与城市规划要求,优化管廊的标准断面。首先对原有入廊管线进行线路需求的明确,然后在城市需求与规划的基础上确定管廊的布局走向,进而基于AHP法建设管廊选型的评判标准,最后在选型标准的架构中选择不同管廊结构中的最优断面。实验中对于管廊优化后的荷载应变力进行测定,得出在应变为0时,优化后的荷载为5 kN/m^(2),而优化前的荷载约为4.3 kN/m^(2)的结果,意味着优化后的地下管廊能够承受更多压力,具有更好的承载性和延性,达成了基于AHP法的管廊使用寿命更久的优化目标。In the widespread construction of underground pipe galleries,due to the age,the original design of the pipe gallery is slightly outdated.Therefore,an optimization of the standard section selection for urban underground cable line comprehensive pipe gallery based on the AHP method is proposed.In the design and planning of the original pipe gallery,the standard cross-section of the pipe gallery is optimized in accordance with the requirements of the times technology and urban planning.Firstly,clarify the route requirements of the original pipeline entering the corridor,and then determine the layout direction of the pipeline corridor based on urban demand and planning.Then,based on the AHP method,construct the evaluation criteria for pipeline corridor selection.Finally,select the optimal cross-section among different pipeline corridor structures in the framework of the selection criteria.In the experiment,the load strain force of the optimized pipe gallery was measured,and it was found that when the strain was 0,the optimized load was 5 kN/m^(2),while the load before optimization was about 4.3 kN/m^(2).The result indicates that the optimized underground pipe gallery can withstand more pressure,has better bearing capacity and ductility,and reflects the achievement of the optimization goal of a longer service life of the pipe gallery based on the AHP method.
