摘　　要：在回顾动力机器基础振动学科在我国发展历程的同时,指出该学科发展中仍需要进一步研究的课题。重点对与地基弹性刚度和阻尼有关的问题、桩基的竖向刚度问题、地基的参振质量问题、弹性波在土体表面的传递、高速机器作用下框架式基础的振动计算以及弹性半空间理论体系和质弹阻理论体系中的有关问题进行论述。It is made that a fundamental indroduction to vibration discipline for machinery foundations which developed in China. Meanwhile, it is pointed out that some subjects need to be further studied. It is emphasized on these problems concerned, such as the elastic rigidity and damping of bases, the vertical rigidity of piles, the problem of participationvibration-mass of bases, the elastic wave propagation in soils, the problem of vibration computation of frame foundations and the relevant problems of elastic half space theory and mass-elasticity-damping theory.
