簡易ネットワークによるフィルダム貯水池からの漏水量予測

抄録

The paper describes a new method to predict a quantity of leakage through a fill dam and subsoils. The main point of this method is to construct a network model for geological structure within a flow region. It is made of some nodal points and branches. The nodal point, which shows a soil deposit, is an imaginary spatial coordinate. The branch, on the other hand, shows a groundwater flow conduit. It has substantial parameters to prescribe the groundwater flow in the model, such as permeability, thickness and length of soil layer. These values can be given from boring and in-situ test results. In this study, however, they are found to be widely scattered even in the same branch. The Monte Carlo simulation helps us calculate the quantity of leakage considering those scattered values.
