摘要
【目的】研究影响动力基础竖向振动特性的关键参数——地基抗压刚度。【方法】采用方程对等法对弹性半空间理论进行简化,修正了地基抗压刚度的计算公式。【结果】得到了能较好地反映基础竖向振动、基底面积和基底压力等诸多因素影响的地基抗压刚度计算公式。【结论】归纳出有关地基抗压刚度的变化规律,为更准确地确定动力基础系统的动力参数提供了参考。
【Objective】 This paper studied the ground pressure resistance which is the key parameter of vibration characteristics in erect orientation of dynamic foundation.【Method】 This project revised the formula of the ground pressure resistance by applying the reciprocity law equation to simplify the theory of elastic half-space.【Result】 In this paper,the formula of the ground pressure resistance which can reflect the influence of many factors such as the vertical vibration,the base area of foundation,the pressure of foundation and so on,was obtained.【Conclusion】 The changing law of the ground pressure resistance provides valuable reference for us to determine the parameters of vibration dynamics of foundation system accurately.
