摘要
利用群桩基础三维计算程序 ,分析了桩基参数对群桩基础单桩横向刚度影响 ,并进一步得到了单桩横向刚度与桥墩自振频率的关系 ,使人们在利用桥墩自振特性对桥墩刚度进行评价时 ,能注意到桩基参数的影响 ,从而经济有效地设计或加固桥墩基础。
In this paper,the author uses three dimension analysis program to analysis the effect of pile foundation parameters on lateral rigidity of single pile and bridge pier nature frequency,it can make people take more notice of the parameters which affect the bridge pier rigidity greatly when people assess the bridge pier rigidity though the nature frequency,so people can design and strengthen bridge pier economically and effectively.
