| 摘 要： | 在海域深厚层淤泥(＞28 m)条件下,对定向滑移爆炸挤淤悬浮式防波堤施工技术,从堤头抛石加载、爆炸挤淤爆破参数选择、循环进尺控制、两侧爆夯等方面进行阐述.在施工过程中采用“体积平衡法,沉降观测,钻孔勘探”等检测手段进行监控,保证爆炸挤淤悬浮式防波堤地基质量,工期短、费用低、沉降小,值得在类似工程中推广应用.

| Abstract: | This paper discusses the construction technology of directional slip blasting compaction treatment for the foundation of suspended breakwater from the riprap loading of dike head, parameter selection of blasting compaction, circulation measurement control, as well as tamping compaction of both sides, which is under deep and thick silt ( > 28 m ) conditions of sea area. Monitoring through volume equilibrium method, settlement observation, and drilling exploration, the blasting compaction quality is guaranteed, and the engineering is characterized by short construction period, low cost and small settlement. Thus the technology is worthy of popularizing in similar engineering. |
