高速公路中央分隔带槽形混凝土护栏的开发研究

Development Study of Trough Concrete Median Barriers of Expressway Divider

简要介绍了高速公路中央分隔带槽形混凝土护栏的开发过程 ,提出了改进后的中央分隔带混凝土护栏的定型尺寸。研究结果表明 ,改进后护栏不仅造价降低 。

The development process of trough concrete barriers of expressway median divider are introduced briefly in this paper. The measurements of trough concrete barriers improved are put forward here also. Results of this study show that the costs of the concrete barriers are decreased but protect effect for traffic collide improved.
