| 摘要: |
| 用强夯置换石碴桩及加筋土的施工方法，对宁波北仑港２０万吨级矿石码头堆场地基进行加固。试验现场模拟使用荷载最不利组合，经直接加载验证，能提高加固后的地基承载力，并获得了加载过程中地基上的应力与变形的增长过程，以及对斗轮机基础的影响等。 |

| Abstract: |
| A construction method of soil improvement is introduced by compaction and replacement of stone ballast columns and reinforced earth on the ore dock of 200000t Beilungang Harbour in Ninbo. Field measurement is conducted by the most disadvantageous composition of working loads. The strengthened foundation is gained in the bearing capacity under the field loading test. The development of stress and strain of the foundation soil and the impact on the foundation of the bucket carrier are obtained in the loading period. |
