Characterization of soil conditions must be able to provide valid and representative parameter values for geotechnical analysis purposes. Soil shear strength is one of the main parameters required. This parameter can be measured directly in the field or from soil samples tested in the laboratory. In this case, there are many factors that determine the advantages or disadvantages of the two test locations. Field tests have the advantage of samples that are relatively undisturbed and depict field conditions as they are. Laboratory tests have shortcomings such as disruption to the sample collection process and sample delivery process. To minimize this influence on test results, field testing is one solution. In previous research, a direct field shear test tool was developed to accommodate the things mentioned. However, many difficulties are encountered when field tests are carried out with various variations in crucial soil parameters that influence the shear strength of the soil. This research shows the importance of combining soil shear strength testing in the field and laboratory for random fill in dam construction.
The general objective of this activity shows the importance of field and laboratory direct shear testing to comprehensively evaluate the shear strength of random fill materials.
