Research of Base Form for Detached and Re-Installed Concrete Bridge Barrier
To meet the requirements of construction convenience and protection level for concrete bridge barrier, this article researches the base form of detached and re-installed barriers. Considering integrity and dismounting convenience, four base forms were put forward such as anchor bolt connected base, outside embedded base, inside embedded base and steel bar welded base. The four base forms were compared through computer simulation, bogie test and analysis of construction convenience. The researches show that there are more probability for inside embedded base and outside embedded base to overturn in practical application. The anchor bolt is likely to cause stress concentration of connection location, and difficult to install. Rigid connection between barrier and bridge frange plate was formed by base steel welded with anchor plate, and so the integrity is better and the construction is convenient and feasible. And so steel bar welded base is the best and suitable for application in the project.
