| Abstract: | Taking the construction in subway tunnel with the technique of horizontal rotary jet grouting pile pre -consolidation as an example, this paper modified the excavation construction with the numerical analysis soft of MIDAS - GTS. Through the analysis of the simulation results, the paper discussed laws and characteristics of the arch displacement and arch stress, stratum displacement and stratum stress with the technique of horizontal rotary jet grouting pile - arch pre - reinforcement in excavation construction ; and put forward construction proposals as reference of engineering technology personnel for similar projects. |
