综合管廊的区间设计

为进一步完善城市地下综合管廊工程设计理论,提高综合管廊工程设计的科学性与合理性,基于大量综合管廊工程设计实践,提出将“区间”概念应用于综合管廊工程的总体设计。通过对综合管廊功能需求和入廊管线技术要求的分析,给出综合管廊各类“功能区间”的定义、特征; 通过进一步分析综合管廊各类功能区间的相互关系和重要性,提出通过功能区间构建具备复合功能属性、可复制的“单元区间”,再通过单元区间的复制串联实现综合管廊总体设计的系统布置方法。最后,提出以“单元区间”为核心理念的综合管廊“区间设计”的定义和一般方法,以期为综合管廊工程系统布置提供一种新的设计思路。

Section Design of Utility Tunnel

In order to further improve the design theory of urban underground utility tunnel and help to design more scientifically and rationally, the concept of "section" is summarized and applied to the overall design of utility tunnel after large number of engineering practice. Based on the analysis of the functional requirements of utility tunnel and the technical requirements of access pipelines, various "functional sections" in utility tunnel are defined and characterized. And then, through comprehensive analysis of the interrelation and importance of various functional sections, the replicable "unit section" with compound functional attributes are constructed based on functional sections. Meanwhile, through duplication and series connection of unit sections, system layout of general design of the utility tunnel can be conveniently built up. Finally, by taking the "unit section" as the core concept, the definition and general method of "sectional design" of utility tunnel are proposed, which provides a new design method for the overall layout of utility tunnel′s engineering system.
