Abstract: In this study, a latex membrane with a diameter of 50 mm and thickness of 0.5 mm is used to encase an injection hole. The gap between the membrane and the nail rod is fixed to achieve compaction grouting and to ...

Abstract: Excavation leads to unloading rebound and stress redistribution in the soil of a slope near the excavation face. The process of reequilibrium of the stress is followed by large deformation or even failure of the slope. In ...

Abstract: A finite-element model was adopted to numerically simulate compaction-grouted soil nails with multiple grout bulbs. The numerical model was first verified by the corresponding experimental results. Then a series of numerical ...

Abstract: An important research topic in reinforcing deep soft soil slopes is the pullout distribution of a long anchor with multiple grout bulbs under various factors. The nonlinear variation between the compaction effect and grout ...

Abstract: This paper presents a work to define four fundamental concepts, namely, buoyant force, submerged unit weight, seepage force, and critical hydraulic gradients, for saturated geomaterials including soils, rocks, and concrete ...

Abstract: This article puts forward a quantified characterization method of micro- and macrocontacts of granular materials. The microcontact is defined as the contact surface with two voids in its two ends. The macrocontact is defined ...
