摘要
爆破挤淤置换法是近岸工程处治厚度小于16m淤泥层的重要手段。某堤防工程厚达30m淤泥层的现场处治,采用预先挖泥与爆破挤淤相结合的施工方法,解决了深厚淤泥中基础难以落底的难题,达到了设计要求。结合该工程实例,分析了深厚淤泥层爆破挤淤法的技术关键,为类似工程提供借鉴。
Explosive sludge-extruding displacement is an important method used in coastal engineering for managing silt layers less than 16 m thick. However, breakwater engineering requires construction in silt layers up to 30 m thick. Dredging and blasting compaction offers an effective method for installing deep foundations in silt, while still meeting design requirements. We discuss this method, and the technological requirement for it, using the example of a breakwater constructed in a thick layer of squeezing silt. The methods employed in the project provide a suitable reference for similar projects.
