Abstrct
A finite element method of analysis utilizing the generalized plane strain approach has been developed to analyze three dimensional stress, strains, and displacements of skew soil nailing walls. This paper explains the fundamentals of analytical approach and the effect of the nail skew angle. Analytical computer parametric study has been conducted to investigate the effects of the nail skew angle of the soil nailing wall. As a results of this study, the generalized plane strain finite element solution method is proved to be versatile enough to easily incorporate the complicated geometry and loading condition as well as the non-linear material properties.

1. Introduction
The benefits of utilizing soil nailing walls in maintaining stable excavations and slopes have been known arrng geotechnical engineers to be very date, virtually all soil nails have been
installed on a plane perpendicular to the facing wall with certain inclination angles to the vertical. However, when the soil nailing wall is to be applied at irregularly shaped areas, such as the L-sh aped corners and U-shaped extrusions, it is inevitable to align the soil nails at horizontal angles othe
