| 摘 要： | 强夯法是地基处理的一种常用方法,而确定强夯影响范围是强夯法应用的关键。结合某港口工程地基处理的实测资料,分析强夯振动在深度和广度上的影响范围,进而得出振动的位移、速度、加速度随距夯击点距离增大而逐渐衰减的曲线关系式。

| Abstract: | Dynamic compaction is one of the common methods for site improvement.But the influence zone of dynamic compaction often can not be estimated well,which has become a problem restricting the wide application of the method.This paper examines thefield measured data during the site improvement with the dynamic compaction at a harbor.,The influence zone in the ground in terms of the depth and horizontal distance is presented from the field monitored data.The monitored data include the ground vibration displacements,velocity and acceleration at different depths and distances during the impacting of the hammer.The vibration displacement,velocity,and acceleration against the depth and distance are plotted as the attenuation curves for the assessment.of the tamping. |
