CONSTRUCTION ON SHEAR STRENGTH RELATIONSHIPS BETWEEN TRIAXIAL COMPRESSION TEST WITH UNCONSOLIDATED UNDRAINED (UU) AND VANE SHEAR TEST (VST) FOR SOFT SOIL IN DANANG

Abstract

Shear strength, cohesion and the internal friction angle are very important parameters in calculating and designing the embankment constructed on soft ground, but it is very difficult to determine them. In order to exactly determine the shear strength of soft soil, it is necessary to combine UU test with different models and the in-situ VST. However, experimental work on the Triaxial Compresion Test with Unconsolidated Undrained (UU) and the Vane Shear Test (VST) for Soft Soil in Danang so far has not been synchronized. This paper presents two findings and confirmation to evaluate coefficient of determination and shows the ability to use the equations for calculation indicators of soil strength mechanical applied for designing and dealing with soft soil in the studied area.
