【Abstract】 This paper studies the statistical method of hydraulic structural size random variables and the influence of size uncertainty on reliability of hydraulic structure. Engineering examples are given in this paper.The calculated result shows that the structure reliability tends to decrease due to size uncertainty of hydraulic structure so that we must pay great attention to them in structural design and construction.更多还原
