Analysis of Seismic Performance of Underground Comprehensive Pipe Gallery Based on Response Displacement Method
More and more attention has been paid to the seismic design of underground comprehensive pipe gallery with the popularization of the construction of underground comprehensive pipe gallery.Seismic response analysis has been carried out for an underground comprehensive pipe gallery in Xuzhou,Jiangsu Province by using the response displacement method.Based on the change in bending moment and axial force subject to seismic action or not,significant increase of bending moment can be found at the bottom of side wall and the mid-span of bottom slab of the pipe gallery by considering seismic action,however,decreased bending moment occurs at other locations under seismic action.The change in subgrade coefficient within a certain range has little effect on the change in bending moment of pipe gallery under seismic action subject to a constant thickness of overburden.
