Prediction of soft clay soil settlement using normalized rotational multiple yield surface framework (NRMYSF) / Hamzah Abd. Hamid

The prediction of soil settlement in geotechnical engineering can be challenging, primarily due to the influence of moisture content on soil shear strength. A reduction in shear strength can lead to increased soil settlement. In this research, the Normalized Rotational Multiple Yield Surface Framewo...
