前言 为了配合铁道部提出的铁路工程技术规范修订工作,铁道部科学研究院的有关同志最近提出了开展铁道建筑安全度(可靠性)的研究和制订《铁路工程结构统一设计原则》的建议,得到了有关方面的重视。本文根据近年来国际上和国内在工程结构可靠性理论方面的发展情况,对以可靠性理论为基础修订我国铁路桥梁设计规范的问题提出了一些初步意见。
Preface In order to cooperate with the revision of railway engineering specifications proposed by the Ministry of Railways, relevant comrades of the Academy of Science of the Ministry of Railways recently proposed to carry out researches on the safety of railway structures (reliability) and formulate the “unified design principles for railway structures” The attention of the parties concerned. Based on the development of reliability theory of engineering structure both in China and abroad in recent years, this paper puts forward some preliminary opinions on the revision of the design rules of railway bridges based on reliability theory.
