Finite Element Analysis of Plane Strain Problems with PS-NFAP and the CAP Model - User's Manual

摘要

The user's manual describes the operation of PS-NFAP, a finite element program developed for the analysis of plane strain problems with the cap soil behavioral model. In addition, two programs (CPCALC and CAP) that assist in calculating the cap model parameters from typical soil tests results, a preprocessor program (AUTOGEN) that generates the PS-NFAP input file, and an auxiliary program (NFMINX) that optimizes the FE mesh node numbering are described. PS-NFAP has special features for analysis of reinforced and unreinforced embankments constructed on soft ground. A detailed example to illustrate how the series of programs are used to analyze a reinforced embankment is given. The programs are written in FORTRAN IV and FORTRAN77. They are implemented on two computer systems: (1) IBM 3083 mainframe using VS-FORTRAN; and (2) the series of IBM personal computers with a math co-processor chip using Ryan-McFarland FORTRAN, version 2.0 (Ryan-McFarland, 1985).
