用近似解析法分析了基础竖向振动的非线性特性，由此建立起基础共振频率、扰力幅值以及地基土动力特性参数间的理论关系，并将其与实验数据进行了比较。本文结果对动力机器基础设计、用共振法测定地基的变形模量和承载力具有实用价值。
The approximate analytical method was used to analyze the nonlinear characteristics of the foundation vertical vibration. Based on this, the theoretical relationship between the fundamental resonance frequency, the amplitude of the disturbance and the dynamic characteristics of the foundation soil was established and compared with the experimental data. The result of this paper is of practical value for the foundation design of dynamic machines and the determination of the deformation modulus and bearing capacity of foundation by resonance method.
