甘肃省白银市某市政道路与铁路交叉设计方案探讨

Discussion on Design Scheme of Intersection of Municipal Road and Railway in Baiyin,Gansu Province

随着城市规模逐渐外延,部分城市道路与企业铁路线发生交叉,这些交叉点往往成为制约工程顺利开展的“瓶颈”,节点工程方案的优劣将对企业远期发展及城市未来交通的走向产生一定的影响,因此权衡此类设计方案的利弊尤为重要。以道路跨越两条小间距铁路线为实例,通过对拟建道路周边的建设条件、节点方案及技术经济指标等定性与定量方面的分析,提出了推荐设计方案。设计实例经验可为类似工程提供一定的实践参考和方案借鉴。

With the gradual extension of urban scale,some urban roads and enterprise railway lines cross.These crossing points often become the"bottleneck"restricting the smooth development of the project.The advantages and disadvantages of these node engineering schemes will have an impact on the long-term development of the enterprise and the future direction of the urban traffic.Therefore,it is particularly important to weigh the advantages and disadvantages of such design schemes.Taking a road across two small-distance railway lines as an example,through the qualitative and quantitative analysis of the construction conditions around the proposed road,node scheme and technical and economic indicators,the recommended design scheme is put forward.The discussion of this design example can provide some references and examples for similar projects.
