摘要
采用最小二乘法和曲梁理论在直拉伸这种最危险受力情况下,给出任意规格尺寸有挡与无挡锚链的最大应力简易计算公式,在实际使用中是非常方便的,大大提高了锚链的设计精度.
Now in the design of anchor chain, the design of intensity using nominal stress is generally employed because of large work load in calculating limit stress and difficulty in getting accurate solution.There is great error, so this leads to the occuring of accident and the wasting of material.Using least square method and the oritial analysis in the most dangerous case of the anchor chain under tension, limit stress formula of stud and studless anchor chain in arbitrary dimension is given.So it is very convenient in using actually and it raises precision of designing the anchor chain.Finally examination is performed on φ28A2 stud anchor chain.
