酒泉市飞天路穿越高速公路方案比选研究

Comparative Study on Scheme of Feitian Road Crossing Expressway in Jiuquan City

随着城市经济发展及空间拓展,道路穿越高速公路的项目越来越多。为了说明穿越方案的比选过程,以酒泉市飞天路穿越G30连霍高速公路项目为实例,根据施工工法、高速交通保障措施、地区施工技术力量、项目施工社会矛盾、工程造价等因素对穿越方案的影响,同时结合场地现状设施及地质情况,对其进行了多因素综合比选,最终选取了与之相配的路改桥方案。所得结论可为同类工程提供有益的参考。

With the development of urban economy and the expansion of space,there are more and more projects of roads crossing expressways.In order to illustrate the comparison and selection process of crossing scheme,taking the project of Feitian Road crossing G30 Lianhuo Expressway in Jiuquan City as an example,the multi-factor comprehensive comparison and selection are carried out according to the influence of construction method,high-speed traffic supporting measures,regional construction technical strength,social contradictions in project construction,engineering cost and other factors on the crossing scheme,and combined with the current site facilities and geological conditions.Finally,a scheme of changing road into bridge suitable for it is selected.The obtained conclusion can provide the useful reference for similar projects.
