Subway Tunnel Construction Period Nonsaturation Soil Body Settlement Anamorphosis' Injected Reinforcement Control Technique Research

This text depend on subway 10 line in beijing engineering construction, pass sampling at field,interior triaxial test and electron scanning to study microstructure and mechanical of clay,silty clay and sand clay, contrast analyse variant property of soil microstructure and mechanical in injecte reinforcement fore and after, research unsaturated soil injecte reinforcement mechanics,study effect of soil microstructure and mechanical through injected material. and apply to its related data to calculation mode's numberical value. Finally, combine previous research findings and exploration research date at field,and make use of three-dimensional limited difference software flac3d established to reflect formation actual distributing statu's numeric analysis model,to evaluate the quality of the inject result.
