dc.description.abstractThe personal computer program MOVEX, a program for the design of structurally supported excavations to limit X lateral ground movements in clay soils, was revised and updated. A key element in the program, the method of determining factor of safety against basal heave, was fully rewritten. Seven case histories were examined to evaluate the program capabilities in predicting movements. Two important improvements to the program include adding allowances for possible anisotropic strength variations in the soil layers, and for wall movements caused by excavation before supports are added to the wall. The latter issue is relevant inasmuch as such movements are present in almost all excavations to one degree or another. The program output was also updated using a streamlined and more informative format. Disclaimer statements were added to certain areas to notify the user of program limitations. Movement calculation methods were improved by removing several errors and adding a linear interpolation feature which eliminates our earlier problem with jumps in predictions as certain parameter horizons were passed. Finally, the Fortran program was reorganized and comment statements were added to provide a more flowing and readable style, and a new User's Guide was developed to reflect the new program.en
