笔者在分析研究多项工程打（压）桩施工过程中，对实测的拉倒孔隙水压力、桩侧正负摩阻力的“中性点”、桩侧向土体挤压力等变化曲线分析，发现它们的最大值，出现在桩入土深度乘以0．618（黄金分割）的部位。打（压）桩过程中出现的硬层和断桩的部位，也正好符合黄金分割。古老而奇妙的“黄金分割”为桩基侧向压力的估算，找到了简易可靠的方法。
During the process of analyzing and studying the construction of multiple engineering piles, the author analyzes the changes of the measured pore water pressure, the “neutral point” of positive and negative frictional resistance on the side of the pile, and the lateral lateral soil pressure of the pile. Their maximum value was found at the depth of the pile and multiplied by 0.618 (golden section). The hard layers and broken piles that appear during the process of hitting (pressing) piles also coincide with the golden section. The ancient and wonderful “golden section” was an estimate of the lateral pressure of the pile foundation and found a simple and reliable method.
