In enforcement plan , the beam and protect plate , and random resistance are analyzed , in which the normal random variable and maximum stress element as evaluation standard are considered 研究了爐墻的改造,梁和護(hù)板的改造、腐蝕嚴(yán)重的部位的加固方案,分析了梁、柱改造方案的隨機(jī)抗力。
Based on the approach of turning some of the relevant extreme - value - type and logarithmic normal distribution variables into independent and normal random variables , the shear - slipping failure probability of a high arch dam is worked out to be of the order of magnitude of 10 ^ ( - 5 ) by means of second - order moment method 在將部分相關(guān)的極值型與對數(shù)正態(tài)分布隨機(jī)變量轉(zhuǎn)換為獨(dú)立、正態(tài)隨機(jī)變量的基礎(chǔ)上,利用二階矩法計(jì)算得到某高拱壩的剪滑失效概率為10 ^ ( - 5 )量級。
