| 摘 要： | 现有规范中对于根据动探方法评价碎石土的指标虽有明确规定，但其仅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，借助十堰500kV变电站工程强夯施工项目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。研究表明，规范标准偏高，其中变形指标误差要大于承载力误差。 |
| 关 键 词： | 碎石土 强夯 动力触探 载荷试验 |

| Abstract: | The evaluation method of broken-stone soil according to relative standards by means of dynamic penetration is clearly specified. But it is only fit for natural broken-stone soil. This test standard is suitable for artificial broken-stone soil is calling in question. Abased on dynamic compaction construction project of Shiyan 500 kV converting station, this question is studied by contrast on the loading test and dynamic penetration test in same location. It is found that the criterion specified in standards is higher than the real one, and that the error of deformation parameters is higher than loading capacity one. |
