Zusammenfassung:The necessity of earthquake-resistant reinforcement for underground structure in large-scale earthquakes is rising. This paper shows a model test of the reinforcement method using the ground solidification body and its FEM analyses that were conducted to examine deformation characteristics of the reinforced underground structure and the effect of the reinforcement. Target underground structure is RC onebox culvert and the loading tests were performed by using the 1/3 scale RC model. The reinforcement body made with cement and clay was situated on both sides of the structure. The effect of the reinforcement was confirmed by comparing the results of the experiments with the earthquake resistant reinforcement and without it. And elasto-plastic FEM analyses could reproduce the behaviors of the underground structure in the loading test.
