Abstract
When we construct an embankment such as a rock-fill dam, we must examine “the permeability of materials” regularly and control quality. “The permeability of materials” that is one of the most important management items can be calculated by the field permeability test. However, it is difficult to check results speedily, because the field permeability test needs long time, great labor and complex analysis of data. We developed an automatic control system of field permeability test (named Taira-No-Mondo) that can control measurement and analyze data and that can output the test result by a reporting form.
