垂直承载桩传递函数法研究

Research on the Vertical Bearing Piles by Use of Transfer Function Method

本文在现场试验资料的基础上,提出了静载作用下多层地基τ-s曲线簇拟合的归一化方法、经验公式及相应桩顶p-s曲线数值解法,并探讨了利用反力系数研究桩尖土承压性能的问题,计算结果同实测基本吻合。

On the basis of in-situ test data 'this paper presents the method of agreement to the curve group of T-S relationship for multi-layer subgrade under static load, and gives empirical formula, as well as the numerical solution of p-s curve for the pile crown. Investigation is also made on the bearing behavior of supported soil under the pile toe by use of reaction factors.The computed results are basically coincident with the test values.
