摘　　要：爆破挤淤技术是通过埋设在淤泥里的炸药爆炸形成空腔区,抛填石料等路基材料填充入空腔从而实现深厚淤泥层的路基构筑。在潮间带等区域采用该技术,运用铵梯炸药爆破后的炸药残留物包括硝基、苯环等致癌物质,会随着涨落潮扩散至周边海水中,可能对周边海域的水产养殖业产生影响。为了探明潮间带爆破挤淤工艺炸药残留物在海水中的有害成分以及分布等规律,采用紫外~可见分光光度计和液质联用法对炸药残留物进行分析,检测相关潮间带深厚淤泥层爆破挤淤项目中炸药残留物在水和淤泥中的扩散情况。检测后发现爆破后水体中确实存在硝基、苯环等有毒物质。The blasting for the silt squeezing technology uses explosives buried in the silt to explode to form a cavity area and fill the cavities with roadbed materials such as crushed stones to achieve the construction of a highway embankment over the thick soft silty soils.At present,the main explosives used in this blasting process are ammonium ladder explosives and emulsion explosives.This technology is used in areas such as tidal zones.The explosive residues after blasting with ammonium ladder explosives include carcinogens such as nitro and benzene rings,which will spread to the surrounding seawater with the rising and falling tides,which may affect the aquaculture in the surrounding seas.In order to identify the harmful components and distribution rules of the explosive residues in the seawater of the blasting and squeezing process in the tidal zone,the explosives residuals were analyzed with UV-Visible spectrophotometer and LC-MS.The diffusion of explosive residues in water and silt in related tidal zone deep silt layer blasting and silt squeezing projects were detected.After the inspection,it was observed that the toxic substances such as nitro group and benzene ring did exist in the water after the blasting.
