| Summary: | 碩士 === 國立臺灣大學 === 農業工程學系 === 82 === The objective of this study is to discuss the behavior of on
the incline of multilayer soils. Since it is difficult to the
seepage point, the problem is analyzed theoretically
appropriate boundary condition and then the free surface
estimated using Boussinesq equation. By simplifying the
conditions in soil layers, the amount of seepage is calculated
one- dimensional assumption. Theoretical and labortary
study performed to analyze this problem. A sandbox
experiment has conducted. The variation of head is measured at
48 measurement using manometer. Dye tracer is introduced to
observe the and seepage point. Then the seepage flow
equations are sectionally by one-dimensional assumption.
Results show that possible to calculate the amount of
seepage using assumption for the case of one or two layer
aquifer system will have significant errors for three-layers
soils. The of vertical flow has been observed in the
laboratory experiment.
