...Pankaj Sharma; Cristina de Hollanda Cavalcanti Tsuha; Oskar Leonardo Laurani López; João Manoel Sampaio Mathias Dos Santos Filho This technical briefing presents an experimental investigation of the pullout behaviour of helical soil nails with and without cement injection. Large-scale field tests...

...Sergio A. Villalobos; Luis Figueroa; Felipe A. Villalobos; Javier Leyton; Frank Sanhueza Soil nailing stability problems are usually studied under two-dimensional conditions. However, actual soil-nailed walls and potential failure surfaces are in fact three-dimensional (3-D). Seeing that, this work...

...Sirine Sghaier; Souhir Ellouze; Mounir Bouassida; Atef Daoud Glass fibre-reinforced polymer ( GFRP ) bars have emerged as a promising alternative to steel reinforcements in soil nailing, owing to their corrosion resistance and favourable strength-to-weight ratio. Despite these advantages, limited...

...G. L. Sivakumar Babu; R. S. Rao; S. M. Dasaka The soil nailing technique has been used in many applications to improve the stability of excavated vertical cuts and existing natural slopes under precarious conditions. In India the method has been adopted in the field using simple technology, which...

...S. A. Tan; G. R. Dasari; C. H. Lee To reduce computational requirements, soil nail systems are usually modelled in finite elements as plane-strain models in which discrete nails are ‘smeared’ as continuous plates. The interaction of adjacent nails across horizontal spacing is assumed to be perfect...

...X. J. Chai; S. Hayashi Soil-nailing technology has been widely used for the support of excavations, and for slope stability. For the design of a soil-nailing system, the pull-out resistance of the individual nails is of paramount importance. In this study, from an objective of strengthening...

...W. Wehr A new type of soil nailing, called sand anchors, has been developed to stabilise old retaining walls. Sand anchors bear without grout because of the constrained dilatancy of a dense granular material between anchor rod and borehole wall. They are environmentally friendly, can...

...B. R. Srinivasa Murthy; G. L. Sivakumar Babu; A. Srinivas Two 5·0 m high soil-nailed permanent retaining walls, as part of a subway underneath a busy national highway, have been designed and constructed at the Indian Institute of Science, Bangalore. The walls were designed using conventional...
