Abstract: Soil stress measured on buried pipe is not distributed with the figure assumed by present calculation method. Its figure has close relation with relative stiffness between pipe and soil as well as construction method. Therefore, on the basis of stress characters obtained by field measurement and model test, under condition of plain strain, through simulating interaction between pipe and soil with Vlazov Model for interaction analysis, the new method with regard to different buried conditions, different fill-in material around pipe and soil stress status caused by interaction between pipe and soil, etc. is established. A visual computer software is designed on the new method; and calculating buried pipe tool innovation is realized. By using the software, the buried pipe in Shanghai was analyzed and the validity of the method was proved by compared with site measured result.

Key words: buried pipe, interaction between pipe and soil, plane strains, transfer matrix
