上跨式综合管廊工艺设计方案研究

Design Scheme of the Utility Tunnel Across the Expressway

六盘水育德路管廊从六盘水至威宁高速公路上部通过,此段范围内管廊因上跨道路,整个管廊处于一个悬空状态。按原管廊走向设计,结构施工完成后,管廊无法承受育德路上部行车动荷载。考虑行车动荷载,将管廊单独列出与育德路道路完成面平行,并在转角的同时对结构进行标高抬升。通过结构设计优化,此120m范围管廊设计为"上跨式管廊",同时根据此上跨形式,采用改变管廊设计走向的方式,既保证了管廊的使用要求,又使各方单位的道路能够正常通行。

Liupanshui Yude Road utility tunnel is across over a expressway, so it is in a suspended state. According to the original design for this utility tunnel, after structure construction completion, the utility tunnel can＇ t bear the upper dynamic traffic loads. Considering the traffic loads, the utility tunnel is listed separately to be parallel to the surface of Yude Road, and at the corner, the structure elevation should be raised. By the structural design optimization, the utility tunnel at this range is designed crossing utility tunnel, meanwhile, this design form and changing design trend type of utility tunnel can assure the usage requirement of utility tunnel and make the roads passing normally.
