Deformation of soil nailing wall and inner forces of soil nails

The soil nailing wall is widely used, but the theory is not researched sufficiently. Full size experiment of soil nailing wall, which was stimulating practical working progress, was conducted by Institute of Foundation Engineering, China Academy of Building Research, both the deformation observation of soil nailing wall and the inner force measurement of soil nails are introduced. Experiment excavation was 10 meter deep, and soil nailing wall was adopted with 6 storey soil nails. In the experiment, excavation, soil nails and shotcreting were constructed according to practical working progress of soil nailing wall, and tests were done, then soil was mounded to study the soil nailing wall's feature with large displacement. Both the deformation of soil nailing wall and the inner forces of soil nails were researched by combining experiment measurement and numerical analysis. ©, 2015, Editorial Office of China Civil Engineering Journal.
