| 摘 要： | 尝试建立变截面桩的挠曲线微分方程，继而提出了变截面优化桩的概念，并给出了端承桩的一种优化算法。还以圆截面大孔径挖孔灌注桩为例，在桩顶受竖向荷载、水平横向力及弯矩作用时，进行了最轻重量设计。通过计算表明，使用变截面优化桩可使桩的体积减少３０％以上。

| Abstract: | In the paper,a varied cross section pile is taken into consideration.The pile is subjected to horizontal force, bending moment and vertical load.With the finite element method and non-linear programming,the optimal solution to the relationship between the pile's diameter and depth is obtained.As an example the paper shows that minimum weight pile can save up to 49% of the concrete used. |
