摘要
Abstract
By studying the application of shield method in shallow covered conveyance tunnel,the schemes of earth backfill and uplift pile are put forward to address the insufficient thickness of covering layer.The settlement displacement and stress are determined based on finite element simulation.During the construction process,all links were strictly controlled and safety monitoring was carried out.The results indicate that the ground settlement is 3.1 mm,the radial convergence is 2.2 mm,and the vault settlement is 2.7 mm,which are all within the safe range.The research results provide technical reference for similar projects,and promote the application and development of shield technology in tunnel project construction.关键词
