The Integration of conventional 3D seismic data with high-resolution 2D seismic data and cone penetration test (CPT) data from geotechnical jack-up foundation reports has enabled a new late Quaternary geotechnical stratigraphy for the Southern Danish Central Graben area in the North Sea. The shallow subsurface has been subdivided into geotechnical units based on seismic appearance and soil behaviour type. The lateral thickness and geotechnical property variations have been mapped and associated with the existing stratigraphies from adjacent areas in the German and British sectors. The geotechnical variations have also been related to geomorphological features in the subsurface that are a result of the changing glacial conditions over the last 120.000 years. Particularly, buried valleys produce unpredictable geotechnical conditions that require additional evaluation and possibly borehole investigations as well as CPTs. The study synthesizes data from multiple geotechnical surveys and extrapolates the local knowledge from the different sites, providing a better regional understanding of the geology and the geotechnical behaviour of the shallow subsurface.

将常规3D地震数据与高分辨率2D地震数据和岩土自升式基础报告中的圆锥穿透测试（CPT）数据相集成，为北海的Dandan Central Central Graben地区提供了新的第四纪晚期岩土地层。浅层地下已根据地震外观和土壤行为类型细分为岩土单元。已经绘制了横向厚度和岩土属性的变化图，并将其与德国和英国地区相邻地区的现有地层联系起来。在过去的120.000年中，由于冰川条件的变化，岩土工程的变化也与地下的地貌特征有关。特别，埋没的山谷会产生不可预测的岩土条件，需要进一步评估，并可能需要进行井眼调查以及CPT。该研究综合了来自多个岩土勘测的数据，并推断了来自不同地点的当地知识，从而提供了对浅层地下地质和岩土行为的更好的区域性了解。
