地下管廊交叉结构地震动力响应分析

Seismic dynamic response analysis of underground pipe gallery crossing structure

城市地下管廊工程需要设计成环网状才能使其功能最大限度的发挥,而在进行环网状管廊工程设计的过程中,两条管廊相交时会形成丁字形或十字形的交叉口。相比管廊结构标准段,交叉口处结构往往较为复杂,需要合理调整断面,在交叉位置视作整体结构,将衔接处的管线及其他设施包涵在内,因此针对地下管廊交叉口进行地震响应分析,可以对震区综合管廊建设提供有益的参考,对城市综合管廊抗震设计以及综合规划方面有一定的意义。

Urban underground pipe gallery project needs to be designed as a ring network to maximize its function.In the process of ring network pipe gallery project design,when two pipe corridors intersect,they will form a T-shaped or cross shaped intersection.Compared with the standard section of pipe gallery structure,the structure at the intersection is often more complex,so it is necessary to adjust the cross section reasonably,construct the overall structure at the intersection,and include the pipelines and other facilities at the junction.Therefore,the seismic response analysis of underground pipe gallery intersection in this paper can provide a useful reference for the construction of comprehensive pipe gallery in seismic area,and provide reference for the seismic design and comprehensive design of urban comprehensive pipe gallery It has certain guiding significance in planning.
