Abstract:
A rigidity model for the segment rings of shieldbored tunnels is established on basis of different diseases and different segment joint positions of the shieldbored tunnels, so as to study the segment ring rigidity of the shieldbored tunnels. Calculation results show that: 1) The theoretical results coincide with the actual rigidity distribution of the segment rings and have high accuracy; 2) The rigidity model can exactly reveal the rigidity distribution of the segment rings, the segment ring rigidity model established is proper and rational, and the establishment of the segment ring rigidity model is helpful to future researches on the redistribution of the internal force of segment rings after disease occurs to the shieldbored tunnels and it has laid a good foundation for followup studies.
Key words: shield, segment, disease, segment joint, segment ring rigidity, Fourier series
