【Abstract】 Starting from the background of a specific engineering,a comprehensive analysis and testing are carried out for the excavation soil nailing supporting structure by establishing a finite element model,by numerical calculations and a comparative analysis.The internal forces and the deformation characteristics in the whole process of excavating and supporting are further explored,which can provide a better scientific basis for the wider application of this supporting technology at home and abroad.At last,suggestions and warnings are given,and further work concerning this problem is also discussed.更多还原
