某海上风电工程勘察具有勘探点间距远、地层变异性大、测试手段单一的特点。深入研究工程场地的古沉积环境,准确把握各地层沉积年代对定性判别土层的工程性质具有重大指导意义。该文以南黄海西部某海上风电工程项目为背景,通过对南黄海西部古沉积环境演化历史的研究,大致确定了下伏各层土的沉积年代和沉积相,为工程勘察中各层土工程性质的定性判别奠定了基础。
A survey of offshore wind power has the characteristics of long distance between exploration sites, large formation variability and single test method. It is of great guiding significance to deeply study the paleo-sedimentary environment of the project site and accurately grasp the depositional age of each stratum to qualitatively identify the engineering properties of the soil layer. Based on the project of an offshore wind project in the west of the Yellow Sea in the south of the Yellow River, the study on the evolution history of the paleo-sedimentary environment in the western part of the South Yellow Sea roughly determines the sedimentary age and sedimentary facies of the underlying layers of soils. The nature of the qualitative discrimination laid the foundation.
