The results showed that the buckling configuration was helicalcurve for the gravitational tubular under the axial compressive force and torque.
结果表明，受压扭组合作用的有重管柱的屈曲构型为上疏下密的螺旋曲线。

In the paper, theoretical mode of revised logarithmic helicalcurve is discussed carefully, and the methods of calculation and design are also given.
本文对修正对数螺线的理论模型进行了详细的分析，并给出了设计计算的方法。
