对普通单层股钢丝绳和多股钢丝绳工作时内部受力进行分析，推导出多股钢丝绳加载时扭转力矩的计算公式。
The calculation formula of torsion moment of multi-strands wire rope as loaded are deducted by internal force analysis of single-strand wire rope and multi-strands wire rope while working.
理论计算和实际使用效果显示，多股钢丝绳虽然比普通单层股钢丝绳在不旋转性能上有较大的优越性，但仍然存在较多缺陷。
The theory and practical use show that multi-strands wire rope have more advantages than the single-strand wire rope on nor-rotation property, but have still more defects.
