Time-factor considered dynamic allocation method of shield tunnel structure

The invention discloses a time-factor considered dynamic allocation method of a shield tunnel structure. The time-factor considered dynamic allocation method of the shield tunnel structure is that the influence of the dispersion time of water in slurry on the expansion force is fully considered, and a functional relationship between the expansion force and the stopping time is built according to the working time of a shield tunneling machine in each excavating path; pipe piece structures of different types can be dynamically selected according to different stopping times of the shield tunneling machine during constructing the shield tunnel, and therefore, the construction cost of reinforcing an expansive soil layer can be decreased.
