Research Paper (postgraduate) from the year 2022 in the subject Engineering - Mining Engineering, , language: English, abstract: This study used non-experimental approaches to evaluate the shear strength of unsaturated soil. Numerous reasons exist for considering non-experimental approaches acceptable for determining the shear strength of unsaturated soils. One of the primary reasons why non-experimental techniques might be regarded a viable option is because performing tests to determine the shear soils is a complicated and time-consuming operation. Typically, the technique entails a number of operations that need specialized equipment and the execution of methodical stages. If the findings are required quickly, the time necessary to obtain them might be harmful to the entire operation. Due to the fact that engineering processes frequently need fast results, experimental approaches may not be effective in certain circumstances.
