Abstract
In order to analyze the stress state around the projecting buried pipe accurately,the pipe-soil interaction should be considered.Base on the condition of pipe-soil displacement harmony,the pipe-soil interaction boils down to a stress concentration problem of planar elastic medium embedded with an elastic circular tube in gravity field.The distribution functions of stress and displacement around pipe wall are obtained through elastic analysis,and the calculation model of the internal force of the pipe section is simplified.Finally,a case study is carried out,and the results are compared with several other calculation formula of soil pressure in buried pipe.
