高速公路互通式立交设计与施工

Design and Construction of Expressway Interchange

针对高速公路互通式立交的发展历程和设计理念,着重分析了其在现代城市交通体系中的重要性。从交通工程、土木工程和环境工程等多个方面,深入探讨了互通式立交的设计原则,特别是设计过程中须考虑的关键因素,如互通式立交线形技术指标,横、纵断面的线形指标设计等。同时,探讨了高性能纤维混凝土在互通式立交中应用,提出了基于信息化的高速公路云端管理体系。

According to the development history and existing design concept of expressway interchange,the importance of interchange in modern urban transportation system is analyzed.From traffic engineering,civil engineering and environmental engineering,the design principles of interchange are discussed,especially the key factors to be considered in the design process,such as the technical index requirements of interchange and the linear index design of transverse and longitudinal sections.At the same time,the application of high performance fiber concrete in interchange is discussed,and the cloud management system of expressway based on information technology is put forward.
