工程地质方法在海上风电场勘察中的应用研究

Application Research of Engineering Geological Methods in Offshore Wind Farm Exploration

海上风电场类工程项目需要对海底地层结构、土体物理学参数进行测定,研究过程分析了工程地质方法中孔压静力触探试验原理,介绍了设备调试、数据计算的基本方法。再结合具体的风电场项目,对其14#风机建设位置的海底地层开展试验,有效地确定了地层结构,包括淤泥层、粉质黏土层、粉砂层、中砂层,并且计算出各土层的土体饱和重度、压缩模量、有效内摩擦角和相对密实度。

Offshore wind farm engineering projects require the measurement of seabed geological structure and soil physical parameters.The research process analyzes the principle of pore pressure static penetration test in engineering geological methods,and introduces the basic methods of equipment debugging and data calculation.Combined with specific wind farm projects,experiments were conducted on the seabed strata at the construction site of the 14#wind turbine,effectively determining the geological structure,including silt layer,silty clay layer,silty sand layer,and medium sand layer.The saturation density,compression modulus,effective internal friction angle,and relative density of each soil layer were calculated.
