Ground Improvement by a Nonparallel Layout of Soil Nails

Abstract:

Soil nails are components retaining a ground to give it support particular in cases when the ground doesn’t satisfy fully the requirements and it is expected an excessive deformation or the worst a collapse. Today in all geotechnical applications the soil nails are arranged in the simplest way i.e. they are all parallel and almost perpendicular the boundary face of the ground body to be bound. Submitted article is a feasibility study on application the soil nails in another a nonparallel scheme of nails arrangement. The nails are located in two closely adjacent parallel plains. The nails are inclined in each plain with regard to a boundary face of the ground body and the nail inclination heads in opposite direction in each plain. This way the nails build up a quasi-web scheme in the ground. Article analyzes the effect of the quasi-web scheme nails arrangement on the ground and looks for an exact solution to evaluate effect on ground strength and strain behavior. The force balance approach is employed for the exact analysis.
