双层多舱综合管廊设计要点与实例分析

Design Essentials and Case Analysis of Double-layer Multi-chamber Utility Tunnel

随着综合管廊建设的不断发展,纳入综合管廊的管线种类日益增多,综合管廊舱室数量随之增加,需考虑将舱室进行合理布置,从而提高地下空间的利用效率。通过优化管线布局,将综合管廊舱室上下叠放,可有效减少管廊对城市地下空间的占用,为满足城市发展需求提供了新思路。以某综合管廊工程为例,对双层多舱综合管廊工艺设计、结构设计及基坑设计三方面进行分析,总结了双层多舱综合管廊设计要点,为类似工程提供实践经验和参考依据。

With the continuous development of utility tunnel construction,the variety of pipelines brought into the utility tunnel is increasing,which leads to a growing number of compartments within the utility tunnel.It is necessary to consider the rational arrangement of these compartments to enhance the utilization efficiency of underground space.By optimizing the layout of pipelines,the compartments of utility tunnel are vertically stacked up,which can effectively reduce the occupation of utility tunnel in the urban underground space,and provide the new ideas for meeting the development demand of city.Taking a utility tunnel project as an example,the process design,structural design and foundation pit design of the double-layer multi-compartment utility tunnel are analyzed.The design essentials of double-layer multi-compartment utility tunnel are summarized,which provide the practical experience and a reference basis for similar projects.
