Visual Modeling of the Landslide Slopes Stress-Strain State for the Computer-Aided Design of Retaining Wall Structures

Abstract

The report authors have developed a LANDSLIP software package for visual modeling and landslide slopes stress-strain state calculation in JAVA programming language. It has various modifications (flat and spatial versions, various calculation models etc.). The user interacts with the LANDSLIP by means of visual modeling on the Graphics User Interface. The user does not interact with all other LANDSLIP objects, they are completely controlled by the Graphics User Interface. It creates all other objects, modifies, uses, and, if necessary, removes them. The interaction between the user and the Graphics User Interface is performed via the menu system. Using the graphical editor menu, the user can create objects to describe the landslide structure and manipulate the additional sliding surfaces, groundwater lines set and program functions responsible for mathematical calculations and design documentation preparation. The LANDSLIP software package is equipped with interfaces that facilitate collecting data from the MicroStation environment, digital map, and geological database. The geological cross-sections are automatically created, and geotechnical soil parameters are evaluated. The software enables the stability analysis of any slopes or scarps using various calculation methods. It ensures wide opportunities to predict, evaluate and combat natural threats. The LANDSLIP software package results reliability was verified by comparative calculations via similar Canadian SLOPE/W software package at the design office of the “Turów” brown coal mine in Poland. The results differences are within the acceptable limits and depend on the peculiarities of initial-boundary conditions input in various graphic editors, various calculation models, etc.
