| 摘 要： | 为了科学地评价应用动态ＧＰＳ技术鉴别振动特征的能力及可行性，本文设计了若干个振动实验。实验数据的谱分析结果表明，利用ＧＰＳ观测数据可以精确地鉴别出振动特征，如相对位移和频率，并且当ＧＰＳ数据的采样频率为Ｆ时，至少可以分辨出约０．２５Ｆ以下的振动频率。该技术可应用于大型构筑物的安全监测。

| Abstract: | In the paper, some vibrating experiments are designed for the scientific justification and feasibility of using kinematic GPS technology to identify the vibrating characteristics. The spectral analysis results indicate that clear and accurate vibrating characteristics such as relative displacements and frequencies of at least about 0.25F can be derived from GPS observations with sampling frequency F. This capability can be applied to safety monitoring purposes for large structures. |
