在充分考虑混凝土建筑物各种不确定性的基础上,基于混凝土建筑物的结构特点和功能,以河南省昭平台灌区中渡槽建筑物为例,构建了功能函数或失效模式,采用结构可靠性理论计算了各部位可靠指标或失效概率,并科学评估了建筑物的使用性能。结果表明,该方法有效可行,并具有实际应用价值。 Based on the full consideration of the various uncertainties of concrete structures, based on the structural features and functions of concrete buildings, taking the aqueduct buildings in Zhaopingtai Irrigation Area of ​​Henan Province as an example, the function or failure modes are constructed, and the structural reliability Calculated the reliability of each part of the index or failure probability and scientifically evaluate the performance of the building. The results show that the method is effective and practical, and has practical value.
