摘要
地震是造成综合管廊破坏的主要原因之一，综合管廊一旦发生破坏，其产生的后果将比传统埋地管道复杂得多。本文介绍了常见的几种综合管廊接头形式，并对不同的接头形式分别建立有限元模型，选取综合管廊标准段并考虑混凝土塑性损伤模型以及土体本构模型，利用自编程序施加黏弹性人工边界以及等效节点力对不同接头形式下管廊及内部管道进行地震响应分析。结果表明，在不同地震动强度下的最大纵向位移差，整体现浇结构的响应会高于预制拼装结构，且随着地震动强度的增加，响应的差异会进一步增大。两种接头形式下，管廊标准段在地震动作用下的损伤很小，仅在地震动峰值加速度达到 0.4g 及以上时会发生轻微损伤，不会影响正常使用。同一地震动作用下，小管径的管道应力水平会小于大管径的管道应力水平。同时采用橡胶止水带和预应力钢筋的接头形式会比仅采用橡胶止水带的接头形式更有利于降低廊内管道的应力水平。考虑到采用预应力钢筋连接的预制拼装结构会进一步提高廊内管道的安全水平，因此，在成本允许的情况下，不仅要考虑接头的防水，还应该采用预应力筋对相邻节段连接，进一步提升综合管廊的抗震性能。
Abstract
Earthquakes are one of the main causes of damage to the integrated pipe gallery. Once the integrated pipe gallery is damaged， the consequences will be much more complex than the traditional buried pipeline. In this paper， several common joint forms of integrated pipe gallery are introduced， finite element models are established for different joint forms， the standard section of the integrated pipe gallery is selected， the concrete plastic damage model and soil constitutive model are considered， and the seismic response analysis of the pipe gallery with different joint forms and the internal pipelines is analyzed by applying viscoelastic artificial boundary and equivalent nodal force by the self-programmed program. The results show that the response of the monolithic cast-in-situ structure is higher than that of the prefabricated assembled structure for the maximum longitudinal displacement difference under different ground motion intensities， and the response difference will further increase with the increase of ground motion intensity. Under the two joint forms， the damage of the standard section of the pipe gallery under the seismic action is very small， and only minor damage will occur when the peak acceleration of ground motion reaches 0.4g and above， which will not affect its serviceability states. Under the same seismic action， the pipe stress level of the small diameter pipe will be smaller than that of the large diameter pipe. The joint form of combining a rubber water stop belt with a prestressed steel bar at the same time will be more conducive to reducing the stress level of the pipeline in the corridor than the joint form of only a rubber water stop belt. Considering that the prefabricated assembled structure connected by prestressed steel bars will further improve the safety level of the pipelines in the corridor， therefore， when the cost permits， not only the waterproofing of the joints should be considered， but also the adjacent sections should be connected with prestressed ribs to further improve the seismic performance of the integrated pipe gallery.
