有限要素法による浸透流解析と現地への適用について

Abstract

The finite element procedure to formulate the variational principle in the problems ofgroundwater was described and its application to the in-situ problems was discussed. Thesteady state flow analyses were performed in the cases of open cut excavations with sheetpiles and tunnel excavation. Results of the analyses were compared with the results of thein-situ measurements. The nonsteady state flow analyses were also carried out to investigatethe time-dependent free surface change and compared to the laboratory test results. It wasrecognized that the finite element analysis was accurate enough to evaluate the behaviorof the groundwater in the complex soil media qualitatively and quantitatively.
