Failure behavior and mechanism of slopes reinforced using soil nail wall under various loading conditions

摘要: Abstract Soil–nailing technology is widely applied in practice for reinforcing slopes. A series of centrifuge model tests was conducted on slopes reinforced with a soil nail wall under three types loading conditions. The behavior and mechanism failure process the were studied using image-based observation displacement measurements slope, nails, cement layer. nailing significantly increased stability level restricted tension cracks Increasing length improved deeper slip surfaces. slope exhibited significant process, which slippage layer fracture occurred conjunction coupling effect. deformation localization induced by within ultimately developed into surface. delaying occurrence slope. nails recognized as combination pull-out bend deformation. conditions shown to have effect deflection, they consequently influenced its formation sequence.
