地盤統計学のシミュレーションを事前情報とした透水係数分布の逆解析

抄録

Geostatistics is a popular method to infer heterogeneous distribution of hydraulic conductivity. However, there are many cases where enough data to create the detail distribution are not obatined. From the point of view of enviromental and mechanical coupling problems, the fine distribution is better than the coarse one such as zoning method. It is presented in this paper that the full heterogeneous distribution of the finite element model is inferred by Baysian back analysis method. The simulation resutls out of geostatistical approach are used as a prior infromation. Kriged distribution is applied as a average one. It is found that the equivalent heterogeneous model can be introduced by the proposed method and the detail distribution is difficult to reproduce although.
