ABSTRACT
The geometrical information of the slope profile and slip surface shown in an AutoCAD image can be automatically captured by a program coded in Lisp language. These data are imported into the spreadsheet, from which the in-built VBA subroutines will calculate the basic data for slope stability analysis, such as weight, pore pressure, shear strength parameters of each slice. The various limit equilibrium methods for slope stability analysis have been arranged in separated sheets, which calculate the factors of safety in a completely transparent format. The conventional slope stability computation using software is still a luxury undertaking for most geotechnical engineers. The chapter describes the technical details of the graphic acquisitions and spreadsheets facilities and discusses the concept of establishing a library of slope stability analysis programs shared through web. The integral and explicit forms for slope stability analysis make the procedures of calculating factors of safety in a Spread Sheet very simple and straight forward.
