Field performance of a hybrid reinforced earth embankment built adjacent to a slope with narrow fill space

[[abstract]]This paper presents a field monitoring results on the performance of a hybrid reinforced earth embankment, used for mountain roadway, built adjacent to a slope with narrow fill space. The hybrid reinforced earth embankment incorporates reinforced earth embankments with soil nails which are installed to the existing ground. To investigate the effectiveness of soil nails connected at back of a reinforced earth embankment, a field monitoring program on reinforcement stresses and nail forces in the hybrid reinforced earth embankment was set up for an 8-m-high earth embankment. The performance of the embankment during construction and under various loadings, including static and traffic loadings, was investigated and discussed
