| 摘 要： | 以桩的荷载传递函数为基础，考虑桩－土（岩）共同作用，从理论上推导了桩身荷载与沉降关系的数值模拟的迭代模型。通过数值模拟分析得到桩顶的P－S曲线，可做为确定桩的承载力的依据。经过对工程实例的计算与实测对比分析，证明该理论可靠、方法简单，且具有较好的实用性。计算得到的P－S曲线与实测的曲线非常吻合。 |

| Abstract: | A numerical iteration method for determining load-settlement relationship of a single pile is developed considering the pile-soil(or rock) interaction. The P-S curve of such a pile is obtained and can be used for calculating the load bearing capacity of the pile.Comparison between the results obtained by the proposed method and the measured data is made; and close agreement has been found. It is shown that the proposed method is theoretically reliable, simple in application and useful in practice. |
