摘要
根据波动分析理论,建立了考虑土塞效应的管桩计算模型和波动方程,提出了一种计算土塞效应的新方法,可分析打桩过程中任意时刻桩身及桩内土塞任意处的运动状态,并编制了相应计算程序,对实际工程的打桩分析结果表明,该方法对土塞效应的判断、沉桩过程的预测等与工程实测数据吻合较好。
According to the wave theory, a computational model and the wave equation of pipe piles are established considering the effect of soil plug. A new method is proposed to calculate the effect of the soil plug, which can be used to analyze the state of motion of the pile and soil plug in the piling process at anytime. And then the corresponding program is compiled. By using this method to analyze the piling of practical engineering, the results show that the calculated values with the proposed method are consistent with the engineering measured data in determining the effect of soil plug and pile driving process prediction.
