防波堤U形槽深厚淤泥软基爆破

Blasting on U-shaped groove deep soft silt foundation of breakwater

结合U形槽深厚淤泥软基的地质地形特点,运用爆炸挤淤理论研究新建围堤、防波堤通过U形槽处理深厚淤泥软基的问题,采用修建子堤作业平台,然后侧向拓宽的施工方法,进行U形槽深厚软基爆破的抛填控制参数和爆破参数设计,并优化施工工艺流程,选择了合适的装药设备。工程应用表明,先子堤、后侧向拓宽法爆破处理U形槽深厚软基可以达到设计要求,可为同类淤泥软基爆破提供参考。

Based on the terrain and geologic characteristics of U-shaped deep silt soft foundation,the problem of new deep silt soft foundation was studied by U-shaped groove using the theory of explosive compaction.The sub-dike operation platform was constructed first,and then the lateral expansion of the construction method was applied.The parameters of cast filling control and blasting of U-shaped groove deep soft foundation blasting were designed.The construction process was optimized and the appropriate charging equipment was selected.The engineering application showed that the method could meet the requirements of construction,which can provide a reference for similar U-shaped deep soft silt foundation blasting.
