芜湖-合肥高速公路路基拼宽方式研究

Study of the Wide Subgrade Treatment in Wuhu-Hefei Improvement Project

以芜湖-合肥高速公路陇西至林头枢纽段改扩建工程为例,结合老路路基防护、超高排水、通道净空不足及路面良好、交通量大等主要特点,进行造价、交通组织便捷性、施工效率等对比,得出单侧拼接优于两侧拼接的结论,并提出单双拼的适用性条件。

Taking the reconstruction project of Wuhu-Hefei highway from Longxi to Lintou period as an example,combined with the protection of old road subgrade,super high drainage,insufficient clearance of channel and the main characteristics of good road and traffic,the comparison of cost,convenience of traffic organization,construction efficiency and so on are performed.It is concluded that unilateral stitching is superior to the stitching on both sides,and the applicability of the single and double spell conditions are put forward.
