Application of Horizontal Bamboo Bars in Highway Bridge Embankment Backfill

Abstract:

Because the backfill of highway bridge embankment is not dense enough and the located in the hard and soft transition area, the big settlement that threats the safety of driving usually occurs when influenced by the impact load of high-speed vehicles. According to statistic of investigation of the accidents on certain highway, the difference between settlements in bridge abutment and bridge back is around 32mm to 100mm. This kind of big settlement difference is the main reason for bumping and other problems harming the operation of highway. In this paper we experimentally use horizontal bamboo bars used in the construction of side bridge embankment to deal with the continuous backfill settlement, which is effective. Bar pile to treat the settlement of highway embankment backfill is one of the economical, reliable and effective treatment without constructional occupation of driving lanes.
