Based on the large-span spatial structure of Ordos's airport terminal, an impermanent supporting system arrangement scheme was put forward during the construction of a large-span spatial steel structure. By FEM analysis, the member force and deformation of the supporting system in construction were got and its availability was validated. Therefore, a whole removal scheme of the supporting system was...
Safety construction of deep foundation pit in narrow space is one technology difficulty. Analysis on the deformation of adjacent building during excavation and supporting is the key factor. Taking the deep foundation pit, supporting structure and surrounding buildings as one system, this paper applies the numerical simulation analysis method to carry out the comparative simulation for the changing...
Engineering practices have shown that the stability of tunnel supports have remarkable time-characteristics. Taking Fang Doushan tunnel as an example, stresses of the primary support, anchor axial force and contact laminating between primary support and secondary lining were surveyed and analyzed. Numerical model used 3D-finite element program was built and the time-stability of tunnel support was...
