摘要
本文运用纵向强迫振动多自由度结构和土体等代流变模型 ,对大直径圆筒振动下沉过程进行模拟计算 ,确定在振动锤作用下大直径圆筒的动力响应、筒壁峰值应力和可沉入性 ,并通过工程试验结果验证模拟计算方法的适用性 ,为施工控制提供依据。
Based on the multi-freedom system with vertical compulsory vibration and the Kelvin model of soil,the paper carries out simulation calculation of sinking large diameter cylinder to determine the dynamic response, the peak stress in the cylinder and sinking feasibility.The results can be used to solve construction problems. The adaptability of the model was verified with site observations.
