Description
It is important to evaluate characteristics of tensile strength of foundation and embankment material of fill-dam for the examination of the development conditions of crack which is one of the causes for hydraulic fracturing. Though it is possible to evaluate the tensile strength of hard rock by fixing both ends of the specimen with chucks and making it work directly, it is not possible to use the same method for soft material like cohesive soil. Hence direct tensile test was performed in this research to measure the tensile strength by changing the column type specimen for the compression test into an I-shaped specimen and using the devices that were experimentally-made for the test. Moreover, the stress generated in the specimen was calculated by the FEM analysis and the form of the specimen for the direct tensile test was suggested. It gave useful result for the direct tensile test, with the specimen being further thinned only in the center part of the I-shaped specimen.
