Finally, by means of electrometric method, the stress of the exterior surface of the feed inlet was measured. The curvilinear figure of the stress distribution of the exterior surface was drawed and compared with the results of the finite element analysis. The rationality of theory analysis and the reliability of finite element analysis were verified.

It is shown that the friction force and bulkhead thrust are the main factors of shield thrust setting, while the friction between the cutterhead and soil is the main factors of cutterhead torque setting. Friction force between shield and soil would make front soil of shield upheave, and subsidence of surface soil is induced by ground loss when the friction force between the cutterhead and soil results in the surface settlement asymmetrical distribution.
