摘要
高速公路改扩建工程中桥梁改扩建方案一直是改扩建工程的重点,其直接决定了改扩建工程的工程规模与投资,而既有桥梁的处置方案又是桥梁改扩建的基础工作。以二广高速洛阳城区段改扩建工程为示例,通过对老路上既有桥梁承载能力的分析,对既有桥梁处置的总体设计原则及具体方案进行了研究和阐述。
In the reconstruction and expansion project of expressway,the reconstruction and expansion of bridges has always been the focus of the project,which directly determines the project scale and investment and the disposal program of existing bridges is the foundation work.Taking the reconstruction and expansion project of the luoyang city section of erguang expressway as an example,this paper analyzes the bearing capacity of the existing bridges on the old road,and studies and expounds the general design principles and specific plans of the existing bridges.
