【摘要】 简述了水上高密度地震映像法的原理、使用的仪器设备和数据采集方法,结合实例介绍了水上高密度地震映像法勘探在水利枢纽闸底板基础损坏程度探测、河底抛石厚度和范围调查、河(湖泊)底淤泥厚度探查及在寻找水底障碍物中的应用效果。在检测水利枢纽闸底板受损程度时,采用了瞬时频率和振幅频率谱特征进行综合解释。更多还原

【Abstract】 In this paper,the principle,equipment and data collecting of the high density seismic image method are summarized.It is introduced with the example of the application effect of high density seismic image in survey of damage degree in hydro-project floodgate soleplate base,in search of jackstone thickness and scope on the river bed,in search of silt thickness on the river(or lake) bottom and in the underwater obstacle seeking.The instantaneous frequency and the amplitude spectrum characteristic are synthetically interpreted in examining damage degree in hydro-project floodgate soleplate.更多还原
