摘要
首先提出利用分层位移迭代法计算单杠荷载与位移（桩顶沉降），即Ｐ－ｓ曲线的方法，然后分析单桩Ｐ－ｓ曲线随桩长Ｌ、直径Ｄ、桩身材料弹性模量Ｅ和极端阻力Ｒμ的变化规律，发现一些重要特征和新的规律，最后利用实测结果进行了验证。文章对制定桩的静载试验规则和合理设计桩基础，具有重要意义。
A method to compute the p-s curve of single pile with layered displacement iterative method is proposed first. Then the variational regularity of p-s curve of single pile with pile length L, diameter D,elastic modulus E of pile shaft material and pile toe resistance R. is analysed. Some important characteristics and new regularities are found and verified with measured results. It has an important guiding significance in laying down the rules on static loading tests of pile and designing the pile foundation rationally.
