摘　　要：海上风电项目施工前需开展地质勘察,用以确定海床下土体的物理力学性质、地基承载力及判断土体液化可能性等参数。海床面的沉积物松软且厚度大、饱和状态且易扰动,通常的钻探取样、土工试验等数据指标可能与实际情况存在出入,以静力触探为代表的原位测试技术作为辅助手段,可弥补上述不足情况,逐步在海洋地质勘探领域得到发展。本文结合某海上风电新建工程地质勘察项目,详细阐述了CPT装备及数据采集系统在工程中的应用,并与其他原位测试方法进行分析比较,进而研究CPT技术在海洋勘探领域中的实用性。Geological survey is required before the construction of offshore wind power projects to determine the physical and mechanical properties of the soil under the seabed,the bearing capacity of the foundation,and the possibility of soil liquefaction.The sediment on the seabed is soft,thick,saturated,and easily disturbed,and the data indicators such as drilling sampling and geotechnical testing may differ from the actual situation.In situ testing techniques represented by static cone penetration can be used as auxiliary means to compensate for these shortcomings and gradually develop in the field of marine geological exploration.This article elaborates on the application of CPT equipment and data acquisition system in a geological survey project for a new offshore wind power construction project,and compares it with other in-situ testing methods to study the practicality of CPT technology in the field of marine exploration.
