| 摘 要： | 通过横向锤击桩基桥墩时桥墩振动波形的分析 ,或通过列车驶离桥梁后桥墩余振的分析 ,可以获得桥墩的自振频率 .结合工程实际 ,分析了桩基桥墩的实测结果 ,并与m法计算结果进行比较 ,发现m法计算结果与实际情况符合得较好 ,且在软土地基上 ,系数m的取值对计算结果影响不大

| Abstract: | The intrinsic frequency of a pier can be obtained by analyzing the wave shape of the pier vibration actuated by a transverse impact,or by analyzing the residual vibration of the pier when the train running away from the bridge.In this paper,the measurement data for a single pile under a bridge pier is analyzed and compared with the computational results by using the m-method.It is found that the m-method is good for determination of the load on piles,and the variation of the coefficient m only has a slight influence on the computational results for pile foundations in soft-clay ground. |
