摘要
随着城市化进程的加快与土地资源紧缺矛盾的突出,共线连续高架桥在高速公路中的应用越来越广泛。文章以柯桥至诸暨高速公路工程共线段大悬臂预应力盖梁少支架法施工为背景,从支架设计及优化、支架搭设施工技术和主要安全措施等方面进行了详细阐述,以尽可能减少施工对既有道路交通的影响,达到安全快速施工的目的。
With the prominent contradiction between urbanization acceleration and land resource scarcity,the application of collinear continuous viaducts in the expressway is more and more widely.Based on the construction of large cantilever prestressed bent cap with few brackets method in the collinear section of Keqiao-Zhuji Expressway engineering,this paper expounds in detail from the aspects of bracket design and optimization,bracket erection construction technology,and main safety measures,so as to minimize the influence of construction on existing road traffic and achieve the purpose of safe and rapid construction.
