SOIL NAILING Term Paper
SOIL NAILING FOR STABILIZATION OF SLOPES
Abstract:
After its development in early 1980’s it become widely used in method of providing permanent and temporary support for earth, and stabilization of slope on many engineering projects in world wide. In starting of this period soil nailing was only performed on that project where geotechnical contractor provide this as an alternative to other soil improvements techniques. Now a days soil nailing is accepted only because of its performance and effectiveness. But the question may rise that in which condition this method is applicable or where is this more efficient and why this technique is to be used. Means when, where and why this technique is been applied. Generally the detail of soil nail, installation procedure, its design and testing and also case studies give us information to use this technique or not.
Introduction:
Soil nailing is technique in which retaining walls, soil slopes and excavation are reinforced passively by the help of steel bars or may be by inserting the relative slender element. The structural elements which transfer load to ground in excavation reinforcement are called nails.
The concept of soil nailing was developed in early 1970 in Europe for repairing of earth wall, for stabilization of permanent and temporary slopes and for retaining walls. The first application of this method was done in 1972 in France. According to Chassie 1993 this technique are also applicable to basement excavation (temporary shoring) and for temporary supports for excavation related to tunnels and railroads. As Chassie also said that first record of this application was in United States in 1970’s mid to provide temporary and permanent support for building of hospital. The major use of this technique in US is in earth retention during construction of building and other structures.
Concepts of soil nailing:
Soil nailing is economical technique which enhances the shear strength of unstable in situ soil by
