根据锻锤基础及其地基土所承受的重复冲击载荷的特性,将连续损伤力学理论应用于锻锤基础系统的疲劳损伤问题,分析了地基土在重复冲击荷载作用下的疲劳损伤特性.研究表明,振幅随离基础中心距离增大而衰减,随离基础中心垂直深度的增大而衰减.同时,锻锤锻打引起的损伤增长对地基土表面或地基土深度上各点的最大振幅比都有极大影响.文中得出的结论具有一定的理论价值和工程实用意义.

Based on the characteristics of the bearing capacity of the hammer foundation system and the re?sponse near the soil ground under long time repeated impact loadings,the theory of continuum damage me?chanics has been applied to study the fatigue damage of ground soils in the hammer foundation system. The results show that ratio of maximum amplitude decreases with the increasing of distance along ground surface and the depth of foundation block. At the same time, the increasing of damage value of soils has a big influence on the ratio of maximum amplitude. The conclusions drawn in this paper have some theoreti?cal values and practical significances of engineering to the design of similar engineering.
