Abstract: By using Mindlin solution and boundary element method, the calculation formulas of superimposed stress of surrounding soil induced by bulkhead pressure and friction force during the propulsion of shield tunneling are deduced. According to the space regularities of distribution of ground loss and by image method theory, the calculation formulas of superimposed stress are deduced. And combining the above three part of stress, the total superimposed stress induced by shield tunneling is obtained. Finally, combined with the practice of subway engineering in Shanghai, the distribution law of the superimposed stress caused by bulkhead pressure, friction, ground loss and their combined effect is analyzed. And the analytical results can provide gist for the protection of surrounding construction during the propulsion of shield tunneling.

Key words: Mindlin solution, image method, superimposed stress, bulkhead pressure, friction force, ground loss
