摘要
依据地基动力特性测试规范 (GB/T5 0 2 6 9 97) ,提出了测试桩基竖向动刚度的稳态 敲击激励综合试验法 ,应用实验模态分析技术识别了桩基的模态参数 ,成功地完成了陕西某热电厂试桩的动刚度测试。
In this paper, a synthetic test method is presented based on the dynamic characteristic test criterion of pile. This method combines sine excitation with shock excitation. Using this method, the dynamic characteristics of test piles in thermal power plant are tested. The model analytical technique is used to identify the model parameters of single pile. The vertical dynamic stiffness of the pile can be computed by these model parameters.
