| 摘 要： | 本文介绍的方法是将地基的振动问题等效为质量弹簧体系,并在该体系上附加一级或多级质量块,测出该体系的动刚度及地基土的参振质量;再通过动静关系求得地基承载力。从理论及方法上摆脱了土动力学中求地基土动刚度及参振质量的困扰。

| Abstract: | In this papar,the foundation vibration problem is equalled in effectiveness the mass elastic system.One stage or multi-stage mass blocks is added to this elastic system.Based on the additive mass blocks of elastic system,the rigid of foundation and the vibrating soil mass can be measured and then the foundation bearing capacity can be determined by means of the relation of dynamic and static parameters.The additive mass method theoretically and methodically get rid of the difficult problem of calculating the rigid of foundation and vibrating soil mass and find out the new approach which dynamically measures the foundation bearing capacity. |
