Description

The Sweden weight sounding test is commonly used as a geotechnical investigation method for detached houses in Japan. However, a weak point of this testing machine is located in the difficulty of control of the load scuttled. Consequently, there is a problem in terms of reliability for estimate the undrained shear strength. In the other hand, it is believed that there is a relationship between the resistances by rotation of screw point with the shear resistance of the cohesive soil. In this study, as laboratory experiments, a special vane with the same screw point height and width (diameter) was prepared to evaluate and clarify the relationship of undrained shear of the cohesive soil from the torque of the screw point and special vane. As a result, there are a closely relation for the undrained shear strength of cohesive soil between special vane and screw point. Also, it proposes an equation to estimate the undrained shear strength of cohesive soil by torque value. By field experiments, it can be verify the validity and apply of estimated expressions.
