重庆绕城高速公路路基改扩建技术研究

Research into Reconstruction Technology for Highway Roadbed Surrounding Chongqing

在此以重庆绕城高速公路为例,通过分析不同车型、不同车速的组合确定了各种条件下车行道宽度的取值;同时论述了窄硬路肩不同宽度的应用条件;以及运用回归分析计算不同速度下车辆内侧的安全限值,从而得出了路基横断各组成要素的取值,且用该方法分析计算得到的结果真实、客观、有效。

Taking highway surrounding Chongqing city as an example,and by analyzing the combination of various auto types and various auto speeds,this paper determines the value of highway width under various conditions,discusses the application condition of various widths of narrowing road shoulder,and obtains the value of all elements of roadbed through calculating the safety limits at different speeds by using regression analysis.The results obtained by analyzing and calculating of this method are real,objective and effective.
