单舱综合管廊抗震计算实例

SEISMIC CALCULATION EXAMPLE OF SINGLE-CHAMBER UTILITY TUNNEL

根据相应规范,综合管廊的抗震设计包括两部分内容:对于标准段,采用反应位移法进行抗震计算;对于出线井、吊装口、人员出入口及各类分支井等单元节点则构建空间三维模型,采用土层-结构时程分析法进行计算分析。采用有限元设计软件对某地一处单舱管廊工程进行抗震计算,并对结果进行分析,相关研究仅供大家参考。

According to the corresponding specification, the aseismic design of urban comprehensive utility tunnel includes the following two parts. For the standard section depth, the reaction displacement method is used for seismic calculation. For the unit such as cable well, lifting port, passageway,multilateral wells etc., construct a threedimensional model of space, soil-structure time history analysis was used to calculate and analyze. In this paper,finite element design software is used for seismic calculation of a single-chamber utility tunnel, then the calculate results are analyzed, the conclusion will be for your reference.
