Abstract

When a road embankment fails due to earthquake, it will influence a road network by cutting off traffic at many places largely. Therefore, it is necessary to develop an effective counterplan which restrains a deformation of sliding of the road embankment due to earthquake. Based on an economical earthquake resistant method of construction, a new design technique of slip failure control is presented for evaluating the behavior of road embankment. A way to realize the design technique of slip surface control is by researching crest reinforcement structure. Based on the aspect, this paper proposes a reinforcement method of construction, in which the crest of embankment is reinforced by a geosynthetics. Applying the reinforcement method of construction we firstly carried out a full-scale model test. Secondary, we carried out a centrifuge model test to verify an effect of reinforcement by same method of construction against earthquake. As a result, it was confirmed that the embankment reinforced by the geosynthetics has a high deformation control and earthquake-resistance.
