非地震荷载作用下旧住宅区建筑物的振动现象日益增多。针对某典型老旧住宅小区建筑物在车辆荷载作用下出现的振动现象，通过分析，提出采用钻孔灌注桩排桩的减振措施。采用有限元法模拟了不同桩长的桩基础的减振效果。综合考虑瑞利波对远场的隔离作用和有限元分析结果，40 m为合理的减震桩长度。提出了一种减振解决方案。
Vibration phenomena on buildings in old residential district under non-seismic load are increasing. Given the vibration phenomenon on buildings in an typical old residential district under vehicle load, cast-in-situ bored piles in rows are suggested to reduce the vibration through analysis. Finite element method (FEM) is used to simulate vibration reduction effect of piles with different lengths. Considering analysis of the isolation of Rayleigh wave from far field and the result of FEM, 40 meter is the reasonable length of the vibration reduction piles. A vibration reduction solution is presented.
