摘要
根据砂土中强夯振动结果,分析了砂土中强夯的振动速度衰减规律。研究结果表明:在砂土中强夯引起的振动速度较粘土中小,不会引起周边构筑物的破坏。同时,当夯击点与测点距离 R 大于50 m 时,强夯引起的地基土的振动速度随距离 R 的变化幅度较小。
The attenuation of vibration velocity of sand-soil caused by dynamic compaction is analyzed based on site monitoring.It is indicated that the vibration velocity of sand-soil caused by dynamic compaction is smaller than that of clay;and it can't cause destruction of surrounding buildings.Furthermore,when the distance between the compacted spot and the measured spot is longer than 50 meters,the change of vibration velocity of sand-soil caused by dynamic compaction with variable distances is small.
