摘要
近几年,随着铁路线路的进一步提速及国家基础建设投资的加大,新一轮高标准的新建及改扩建火车站房工程层出不穷。新建及改扩建站房对大跨度、重荷载等使用功能要求的不断提高,使得高效预应力混凝土技术在此类大型工程中得到了广泛应用,并取得了良好的经济效益和社会效益。以广州南站、石家庄站为例,着重介绍预应力混凝土技术在新建及改扩建火车站房中的应用中遇到的难点及解决方法。
In recent years,with the increasing speed and national infrastructure investment of railway line,a new round of high standards of new and renovated railroad station project emerge in an endless stream. With the improving requirements of large span and heavy load,efficient prestressed concrete technology is widely applied in such large project,which obtained the good economic and social benefit.Taking Guangzhou South Railway Station and Shijiazhuang Railway Station as example,this paper introduces the difficulties in application of prestressed concrete technology in detail.
