Radial Point Interpolation (RPIM) meshless method for analysis of soil nail walls

Soil nailing has been widely used as a reinforcing technique to retain excavations and stabilize slopes.The behavior of reinforced soil walls can be understood by studying the state of stress within the reinforced zone. Analysis and design of soil nail walls are usually done by using equilibrium methods.Several parameters influence the behavior of these structures. So that proper assessment of the interaction between the nails and the surrounding soil is very important for the safety and economical design of the composite reinforced soil structure which is not considered properly in typical design process.The purpose of this study is to investigate soil-nail interface in finite element method with meshless method. In this article, RPIM meshless method is proposed for simulation of soil nail walls. Difficulties of methods related to mesh are solved by using this method, especially modeling of thin media, i.e. nail. A code has been developed based on this method and some examples are solved for analyzing the code
