随着科学技术的发展,近代桥梁工程越来越趋向于大型化、机械化和复杂化。为了减轻结构物的自重,缩小断面,提高承载能力,增大跨径,高强度混凝土的应用为此提供了一条有效的途径。国外近年来在这方面的研究和应用已取得相当的进展。本文综合介绍国外的一些试验研究成果及若干实际应用,并提出一些问题和建议。 With the development of science and technology, modern bridge engineering tends to be more and more large, mechanized and complicated. In order to reduce the weight of the structure, reduce the cross section, increase the carrying capacity, increase the span, high strength concrete application provides an effective way to this end. In recent years, considerable progress has been made in the research and application of this field in foreign countries. This article introduces some foreign experimental results and some practical applications, and put forward some questions and suggestions.
