ANALYTICAL STUDY ON BENDING DEFORMATION OF BURIED PIPELINES UNDER SEISMIC WAVE

ZHAI He;LI Peng-cheng;LI Zhi-ming;Ceneral Research Institute of Building and Construction CO.,LTD,MCC Group;  
Based on the Winkler elastic foundation model, the bending deformation of buried pipelines subject to seismic wave propagation is studied. Analytical formulas to deformation and strain of buried pipelines are derived. The results reveal that the axial response of buried pipelines is much larger than the bending response subject to seismic waves.
