Numerical investigation of symmetric settlement of piled and geogrid reinforced bridge abutments

摘要

One of the major problems in highway and railway bridges is the settlement of the bridge abutments,rnwhich its reduction has always been set as the researchers target. Two methods which have beenrnwidely used are reinforcing the abutment with geogrid and abutments on piles. However, in terms ofrnperformance, these two methods have not been compared accurately. This paper describes thernapplication of a two-dimensional finite element program for comparing the performance of these twornmethods. The data from an experimented bridge abutment has been used for verification of modeling.rnThe reduction of bridge abutment`s settlement by pile and geogrid have been analysed andrncompared.
