采用水下及饱和土爆炸法处理软土地基不需大型施工机械和复杂的施工技术。若使用得当,可收到耗人力少、投资省、见效快等技术经济效果,日益引起工程界重视。主要应用范围有:加固易产生振动液化的松散均匀砂层、压实水下抛石、砂砾基床及基土、置换沼泽地淤泥地基土、消除湿陷性黄土地 Submarine and saturated soil blasting method to treat soft soil foundation without large-scale construction machinery and complex construction techniques. If properly used, it can receive less technical and economic effects such as less manpower, less investment and quicker effects, and has drawn increasing attention from the engineering community. The main applications are: to strengthen the loose sand layer prone to vibrating liquefaction, compaction submerged riprap, gravel bed and base soil, replacement of silt foundation soil in wetlands, elimination of collapsible loess
