高能级强夯置换工艺处理地基效果评定

Effect Evaluation of High Energy Level Dynamic Compaction Replacement Method in Foundation Treatment

通过对高能级强夯置换工艺处理场地的具体工程原位测试结果分析,得出对于埋深较深、厚度较大及液化现象严重的粉砂层,采取适当减小主夯点间距、保证排水通畅、减小雨水对场地的浸泡、延长每遍强夯的间歇期、增大插点夯能级及增加满夯遍数的措施,可有效提高地基处理效果。

Through the dynamic analysis of the specific engineering test results in situ replacement processing sites of high energy level dynamic, the results were drawn that for the deep, thick and liquefaction phenomenon serious silt, if some measures were taken such as appropriate to reduce the spacing, ensure smooth drainage, reduce the water on the site of the immersion, prolonged intermittent period of every times of dynamic compaction, increase insertion point tamping energy and the number of the full consolidation, and so on, it would effectively improve the effect of foundation treatment.
