摘要

以某电厂工程场地为例,通过对回填土进行强夯地震效应测试,分析强夯振动的特征及振动衰减规律,评估隔震沟的减震作用、强夯对回填土所形成的高边坡的影响以及对新浇混凝土基础的影响。为回填土地基处理方案的确定提供依据,取得了较好的效果。
Based on power station engineering,the earthquake effect of dynamic compaction is tested in the backfilled soil,characters and vibration attenuation law of dynamic compaction are analyzed. Effects of decreasing vibration of vibration isolation groove are evaluated,both of the high slope of backfilled soil and the fresh concrete foundation influenced by the dynamic compaction are also evaluated,which is provided as the basis for the treatments of backfilled soil foundation.
