| Abstract: | Aiming at the construction of the testing section for a tunnel in Shanghai,this paper emphasized and expatiated on the simulation of the sequence of shield tunneling procedure based on the current simulation methods.The large-scale three-dimensional dynamic model was established and then calculated on a high-performance computing platform with parallel algorithm.The results show the detailed ground deformation,and validate the rationality of this numerical model with monitoring data.The influence of various solving schemes on calculation efficiency was also investigated. |
