| Abstract: | Based upon analysis of the stress and reasons caused the failures of direct-buried heat supply pipeline the major reasons caused the failure of direct-buried heat supply pipeline with larger diameters are elaborated.In addition,questions deserving attention in design of large-diameter direct-buried heat supply pipeline are discussed,which has a certain reference value for similar works. |
