| 摘 要： | 钢筋砼结构的缺陷可能是施工造成的先天性缺陷，也可能是使用过程中的腐蚀性介质环境造成的，分别对其可靠度水平的变化规律进行研究，对维修加固决策具有科学意义。本文根据《建筑结构可靠度设计统一标准》要求，研究了先天性施工缺陷结构及后期使用环境中腐蚀性介质影响下的缺陷结构的可靠度特点，分析了其影响因素，对比了不同荷载特征条件下的缺陷结构可靠度的变化规律，为优化维修决策提供了理论支持。

| Abstract: | The defects of reinforced concrete structures may be the congenital ones caused by construction and they may also be caused by the corrosive media environment. The study of the changing laws for their reliability level is of scientific significance for decision-making in maintenance and consolidation. In accordance with the Unified Standards for Reliability Design of Architectural Structures, this thesis deals with the congenital construction-defect structures and the reliability characteristics for defect structures under the influence of corrosive media in the circumstances of the later-stage use, analyses the influence factors and contrasts the changing laws for the reliability of defect structures under the conditions of different load features, thus providing a theoretical support for optimizing the decision-making of maintenance. |
