| 摘 要： | 桩的中和点和中性点的问题,直接关系到在垂直荷载作用下单桩实际承载力的计算.半个世纪以来,各国土力学家均致力于桩的中性点的试验研究,得到的桩中性点在0.5L～0.9L(L为桩的入土深度)范围内.关于桩的中和点问题,现有教科书和文献资料均未提及.笔者应用黄金分割原理建立的Gan-Chen模式,能正确地计算出:桩的中和点在0.382L处;中性点则在0.618L处.

| Abstract: | The mid|point and the neutral point of pile are directly related to calculation of practical bearing capacity of single pile under vertical load. Since the last half century, the experts in soil mechanics have devoted themselves to making a study of the mid|point of pile, which was found to range for 0^5 L to 0^9 L ,where L stands for the depth of the underground part of pile. while for neutral point, it hasn't been mentioned in the textbooks and reference materials. Based on golden section method, the author has established Gan|Chen model which accurately obtain that the position of neutral point and mid|point is located at 0^382 L and 0^618 L respectively. |
