| 摘 要： | 十堰500kV变电站工程地基采用强夯法进行处理，夯填料为挖方区云母片岩破碎料。规范中对于根据动探方法评价碎石土的指标有明确的规定，但其适用于天然碎石土地基。对于强夯处理形成的人工碎石土地基能否采用该标准，借助于该强夯工程根据静载试验和超重型动力触探对比试验对其进行了研究。

| Abstract: | Ground of Shiyan 500kV converting station project is disposed by dynamic compaction. The compaction material is the broken stone of Mica Schist from excavation area. It is clearly specified for the evaluation index of gravel soil by dynamic penetration in code, which is suitable for natural gravel soil ground. Whether this test standard is suitable for artificial gravel soil ground is studied in the dynamic compaction construction project by the contrast test of static loading test and super-dynamic penetration test. Therefore, the dynamic penetration test standard is effective for the quality control of construction of artificial gravel soil ground. |
