A specimen of bridge pier with the foundation will be constructed. A soil box filled with soil surrounding the pier foundation will be setup. The equivalent force of the debris flow surges will be calculated by a numerical simulation system to be developed by another sub-project about debris flow surge numerical simulation. The calculated equivalent force of the debris flow surges will be applied using hydraulic actuators on the soil to simulate the interaction forces that debris flow applies on the bridge pier and its foundation. Hydraulic actuators will also used to apply equivalent forces on the top of the bridge pier specimen to simulate the dynamic interaction responses of the upper-structure of the bridge system. The upper-structure interaction forces will be calculated by a pseudo-dynamic numerical analysis engine. All of the above components will be networked by a hybrid experiment system to be developed in this sub-project, reflecting the interaction effects among piers, foundations, soil, and debris flow surges. Through the preparation work of this experiment, the hybrid experiment technologies will be advanced, possibly making this experiment the world’s first geo-structural hybrid experiment considering the interactions among debris flow surges, soil, foundation, bridge piers and numerical simulation.大地工程-結構工程實驗複合實驗土石流數值分析土壤-基礎-結構互制geo-structural experimenthybrid experimentdebris flow surgesnumerical simulationsoil-foundation-structure interaction優勢重點領域拔尖計畫/工學院/大地工程與結構工程之動態互制複合實驗
