摘要:
以某综合管廊上燃气舱进风口节点为例,建立二维有限元模型,采用黏弹性人工边界,沿X向输入El Centro波,分析节点在0.05 g、0.10 g、0.15 g和0.30 g,4种地震波峰值作用下的地震响应。研究发现:管廊节点在地震作用下具有良好的整体性能,管廊节点的应力随土体变形的增大而增大;管廊节点隔板与底板及中板部位的应力较大,侧壁与底板及中板的交接处应力值也相对较大,这些部位属于在地震作用下管廊节点的薄弱部位。
Abstract:
In this paper, a two-dimensional finite element model is established by using a two-dimensional finite element model of a gas tank inlet in a utility tunnel. The viscous-spring boundary is used to simulate the El Centro wave along the X-direction. The nodes are analyzed at 0.05 g, 0.10 g, 0.15 g and 0.30 g, seismic response of four kinds of seismic peaks. It is found that the utility tunnel nodes have a favourable overall performance under the action of earthquake. At the same time, the stress of the pipe nodes increases with the deformation of the soil. The stress of the pipe joints and the bottom plate and the middle plate is larger, the stress value of the junction of the bottom plate and the middle plate is relatively large, and these parts belong to the weak parts of the gallery node.
