摘要
根据模型试验研究了打桩振动对黏性土边坡的动力响应(加速度和位移等),分析坡面及坡体内不同位置处的动力响应规律.分析结果表明边坡的坡度越大,加速度峰值和边坡位移越大;相同坡比的情况下,阶梯形坡的加速度峰值和边坡位移要比直线形坡的峰值要小.边坡对输入加速度和位移具有非常明显的放大作用.
According to the model test,the dynamic response of pile driving vibration to the cohesive soil slope is studied,analyze the dynamic response of slopes and different locations in the slope. The results show that the greater the gradient of the slope,the greater the acceleration peak and slope displacements. In the case of the same slope ratio,the acceleration peak and the slope displacement of the stepped slope are smaller than the peak value of the linear slope. The slope has a very significant amplification effect on the input acceleration and displacement.
