摘要
Abstract
In order to study building vibration with different foundations induced by subway operation, a five-story building with the independent foundation or the strip foundation or the pile foundation was modeled. The displacement, the velocity and the acceleration of the floor in the vertical and the horizontal direction ranging from 1~80Hz were analyzed. The results showed that: (1) The displacement, the velocity and the acceleration of the first floor in the vertical direction are larger than those in the horizontal direction for all foundations; (2) The value of the acceleration in the horizontal direction is increased from the first floor to the top floor for the inde-pendent foundation and the strip foundation. The horizontal acceleration is almost the same from the first floor to the fourth floor for the pile foundation. However, the horizontal acceleration of the fifth is bigger than other floors. The vertical acceleration of different floors has no relationship for all foundations.关键词
