摘　　要：建立弹性支撑桩-大直径桩土耦合模型,考虑大直径桩周围土体的三维轴对称振动,求解得到桩周围土体振动响应频域解析解。通过傅里叶逆变换得到桩周围土体振动响应在时域内的半解析表达,同时进行参数影响分析,得到桩周围土体振动响应的规律。Establish an elastic support pile-large-diameter pile-soil coupling model,taking into account the three-dimensional axisymmetric vibration of the soil around the large-diameter pile,and obtain the frequency domain analytical solution of the soil's vibration response around the pile.Obtain the semi-analytical expression of the soil s vibration response around the pile in the time domain through inverse Fourier transform and conduct an analysis of the parameter influences,thereby obtaining the patterns of the soil's vibration response around the pile.
