In this paper , the formulas of dynamic parameters provide good method to determine the dynamic parameters , which can reflect the influence of many factors such as the property of soil , the base area of foundation , the pressure of foundation , the exciting frequency and so on 本文得到的地基刚度、参振土质量和动力影响深度的计算公式能较好地反映地基土体性质、基底面积、基底压力和扰频等诸多因素对它们的影响，为更准确地确定机器基础系统的动力参数提供了一种较好的途径。
Five typical examples concerning pressure distribution under shallow foundation , earth pressure of retaining wall , behavior of a axially loaded bored pile , a metro tunnel constructed with shield machine , and a landslide with tunnels in it are solved successfully , which verifies the validity of the method developed in this paper . at the end , some unsolved problems in the presented method are discussed briefly 第页西南交通大学博士研究生学位论文上述工作完成后，应用该方法成功地计算了浅埋刚性基础基底压力分布、 5刚性挡土墙土压力、钻孔灌注桩承载特性、盾构法施工的隧道的受力及变形、隧道与滑坡的相互作用等儿种有代表性的岩土工程问题，证明了本文方法的正确性及用于岩土工程问题的可行性。
