Evaluation of Design Methodologies for Soil-Nailed Walls

Description: Comparative evaluations of seven soil nail wall design computer programs are described and analyzed. The performance evaluations of the available programs (SNAIL, NAIL-SOLVER, STARS, NAILM, GOLDNAIL, TALREN, and COLDUIM) was accomplished by conducting a number of example analyses. Ten hypothetical cases and five case studies used in the analyses represented common design scenarios. Also examined were the magnitude and distribution of loads on the nails under normal working conditions. This was accomplished by observing the response of soil nails for a number of walls instrumented with strain gages. From this a general approach for estimating nail loads from strain history data was developed.
