Estimation of soil strength parameters based on database with use of Hierarchical Bayesian Model

Key Points

• This research aims to estimate soil strength parameters critical for the design of earth structures like reservoirs.
• Used a hierarchical Bayesian model to integrate generic and site-specific data.
• Created a database from past borehole data to estimate effective cohesion and internal friction angle.
• Compared predicted values with actual measurements to validate the accuracy of the method.
• Successfully estimated effective cohesion and internal friction angle with higher accuracy compared to traditional methods.
• Demonstrated practical applicability of the hierarchical Bayesian model for soil strength estimation in various sites.
• Validated method accuracy through comparison with real measurement data.
