桥梁,作为基础设施的核心部分之一,在高速铁路、高速公路、城市地铁或轻轨国家交通网络的发展中扮演了重要角色。在中国高速铁路、高速公路或客运专线交通基础设计建设中,桥梁的设计和施工经常成为决定性因素。在过去的几十年中,桥梁设计者和建造者把节段预制技术(例如,小节段混凝土精确预制、大尺寸混凝土预制和大尺度钢结构预制)推进到了一个新高度,为交通领域的决策者提供了坚实的技术平台。本文简要介绍了这种先进的预制节段技术及其在世界范围内的著名应用范例。
Bridges, as one of the core components of infrastructure, play an important role in the development of highways, highways, metros or light rail national transport networks. In the design and construction of transportation infrastructure for high-speed railways, expressways or passenger dedicated lines in China, the design and construction of bridges often become the decisive factor. Over the past decades, bridge designers and builders have taken segment prefabrication (eg, precision precasting of small sections of concrete, prefabrication of large-size concrete and prefabrication of large-scale steel structures) to a new height for decision-making in the field of transport Who provide a solid technical platform. This article gives a brief introduction of this advanced prefabricated segment technology and its well-known application examples worldwide.
