影响群桩动力特性的单因素规律研究

ANALYSIS OF DYNAMIC CHARACTERISTIC OF PILEGROUPS WITH SINGLEMRAMETER

本文利用复合平面应变近似法的改进，通过单桩动力特性的分析；进一步分析群桩的动力特性，探讨影响群桩动力特性的因素，分析单因素影响规律，旨在更深入地了解桩基在动荷载作用下的特性，得到了一些有实际意义的结论．

An approximate method of plane strain(Borrow-Novak method) for the dynamic complexstiffness analysis of axial response of pile is appliedin this paper. The results of calculation agree wellwith practical examples. The factors affecting dy-namic characteristics of pile groups are discussed,and a series of relation curves and conclusion areobtained by comparison. All these results are ofpractical value for the design of pile foundation.
