- Abstract
- In this research, model tests have been performed for researching the seepage characteristics in the finite soil slope during the rainfall using a manufactured rainfall simulator. On the basis of the results, it has been analyzed how to change the seepage characteristics due to the duration time of rainfall. We are found that the pore-water pressure was gradually increased as increasing the duration time of rainfall. Specially, at the beginning of rainfall, the pore-water pressure in the middle surface of slope was measured larger than any point. As increasing the duration time of rainfall, the pore-water pressure at the inner part of slope was increased greatly at the collapse due to infiltrating the pore-water within the slope. In the research, it was not easy to get various test results because measuring instruments are high sensitivity and difficult to handle. For the future, the model test results are needed for the various slope angle.
