混凝土的徐变和收缩是长期荷载作用下混凝土结构裂缝宽度扩大的主要影响因素.因受环境条件影响,使其在水工结构中具有较大的不定性,而对水工混凝土结构构件可靠度的影响,目前尚无统一认识及合理的考虑方法.为了正确分析计算长期荷载作用下水工结构限裂可靠度,从多个方面探讨了混凝土收缩和徐变的变异对长期荷载统计不定性构件截面抗力不定性的影响程度,据此采用正常使用极限状态"抗力-荷载效应转换摸式"进行了可靠度分析.结果表明:长期荷载作用下水工结构限裂可靠度比一般的建筑结构高;水工混凝土结构构件裂缝计算公式的可靠度原则对不同

The creep and shrinkage of concrete are the main influencing factors for the expansion of crack width of concrete structures under long-term loading. Due to the influence of environmental conditions, it has a large uncertainty in hydraulic structures, and there is no unified understanding and reasonable consideration method for the reliability of hydraulic concrete structural components. In order to correctly analyze and calculate the reliability of crack limitation of hydraulic structures under long-term loading, the influence of concrete shrinkage and creep variation on the cross-section indeterminacy of long-term load statistical uncertain members is discussed from many aspects, and the reliability analysis is carried out by using the normal service limit state "resistance-load effect conversion model". The results show that the reliability of cracking limitation of hydraulic structures under long-term loading is higher than that of general building structures. The reliability principle of the crack calculation formula of hydraulic concrete structural members is different
