Performance evaluation of a new type of abutment with geosynthetics

초록

This paper introduces new types of abutments reinforced with geosynthetics for railroads to reduce settlement of transition zone between abutment and embankment and horizontal displacement of them. The objective of this research is to develop more economical and better performance abutment. To achieve this goal, firstly we used 2 dimensional numerical analysis to evaluate the performance under train loadings. From the numerical analysis, we found that the settlement of transition zone of them could be decreased to 20% compared with one of existing abutment.
