摘    要:通过浅地层剖面声学探测资料,发现黄河水下三角洲浅表存在局部扰动地层,扰动地层多与负地形相伴生,地层扰动最大深度可达5m。通过对黄河水下三角洲浅表局部扰动地层和其周围正常地层的工程地质调查,对比得出扰动地层的工程地质特性好于周围正常地层。结合已有的水槽试验研究,认为海底浅表局部扰动地层的形成及其工程地质特性的变化是由波浪导致局部土体的振荡滑动造成。

关 键 词:扰动地层  工程地质特性  水槽试验  黄河水下三角洲

Abstract:From the acoustical exploring data of superficial strata,it is found that partial disturbed strata exist in the shallow depth of the subaqueous Yellow River Delta,accompanied by negative topography,and the biggest depth of the disturbed strata is 5 m.Engineering geologic investigation analysis between the disturbed and undisturbed strata,gives the results that engineering geologic characteristics of the disturbed strata are better than those of the undisturbed ones.With the flume experiment,we conjectured t...
Keywords:disturbed strata  engineering geologic characteristics  flume experiment  the subaqueous Yellow River Delta
