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.
Research on the dynamic response of soil around large diameter piles under elastic support
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 ex-pression of the soil's vibration response around the pile in the time domain through inverse Fourier transform and conduct an a-nalysis of the parameter influences,thereby obtaining the pat-terns of the soil's vibration response around the pile.
