- 摘要:
- 本文从分析计算缆风绳拉力的查浦林公式入手,论证了合理确定初拉力,防止在多缆风绳受力系统中缆风绳弧垂变化导致缆风绳及地锚失效的可行性;采用将地锚按工作拉力预拉紧后再恢复至初拉力等方法,防止地锚位移导致缆风绳及地锚失效。
By analysing the Chaplin's formula for calculation of pull force of mooring rope, this paper proves the applicablity of reasonable determining its prepull force to prevent variance of rope arc weight in multi一mooring rope system from causing failure of mooring rope and ground anchor.Using the method, that is, pretensing ground anchor according its work pull force then releasing it until its pre一tension pull, can provent moving of ground anchor from causing failure of mooring rope and ground anchor.1990,3(3): 10-13参考文献：
