Development of Slope Stability Analysis Program KUSlope 3.0

Abstract

Slope stability analysis using the Limit Equilibrium Method (LEM) is complex and time-consuming. Therefore, slope stability analysis software is a tool that enhances analysis efficiency, making it faster and more accurate. Kasetsart University has continuously developed slope stability analysis software for over 30 years. The latest version is KUSlope 2.1, which still has limitations in modeling, visualization, certain analysis cases, and slope reinforcement. The software is developed using C# on Visual Studio, utilizing the Windows application form as the programming platform. C# is popular for analytical programming because it is close to machine language, leading to faster calculations than other languages. This development of KUSlope aims to create a more user-friendly modeling interface, improve analysis capabilities, and add diverse slope reinforcement functions, such as anchor, geosynthetic, soil nail, and pile, to meet user needs. Additionally, it will include probabilistic slope stability analysis functions to assess the probability caused by the variability of soil shear strength, which is used to evaluate risk and failure probabilities. It will also include reinforcement analysis functions using plant roots in the area.
