Zusammenfassung:	To properly determine soil parameters required for performing civil engineering and dynamics simulations on various grounds.SOLUTION: A parameter determination device 1 is a parameter determination device for determining parameters for a particle model used in a ground analysis system, which includes: a triaxial compression test numerical analysis unit 12 that determines parameters so that the adhesive strength and the shear resistance angle of a virtual ground match the adhesive strength and the shear resistance angle of the actual ground with predetermined accuracy; and a pull-out test numerical analysis unit 13 that determines parameters so that the ground reaction force coefficient of the virtual ground matches the ground reaction force coefficient of the actual ground with predetermined accuracy.SELECTED DRAWING: Figure 5 【課題】各種地盤に関する土木・力学シミュレーションを行う際に必要となる土質パラメータを適切に決定する。【解決手段】パラメータ決定装置１は、地盤解析システムで用いられる粒子モデルのパラメータを決定するパラメータ決定装置であって、仮想地盤の粘着力とせん断抵抗角が実地盤の粘着力とせん断抵抗角にそれぞれ所定の精度で一致するようにパラメータを決定する三軸圧縮試験数値解析部１２と、仮想地盤の地盤反力係数が実地盤の地盤反力係数に所定の精度で一致するようにパラメータを決定する引抜き試験数値解析部１３と、を備える。【選択図】図５
