Outline of Final Research Achievements

Swedish weight sounding test (thereafter, called SWS test) is widely used as a research method to evaluate the residential sites. A disadvantage of SWS test is the inability to determine the soil. Suppose that if it is possible to incorporate the determination method of the soil by electrical resistivity using SWS test holes, a lot of infomation will be gained. As a basic research, the auther attempted to clarify the evaluation method of soil fraction content by using a sample of 56 types of laboratory experiments. Furthermore, field experiments of the six sites were performed to confirm the accuracy of the estimated equation from the laboratory test. And auther showed that this estimated equation can be applied with the accuracy of 94% in the field.
