摘　　要：目前海上风电场基岩面的勘察主要有钻探和物探等手段,钻探因其成本高、工期长、钻孔数量较少,难以确定基岩面的分布范围。介绍单道地震法,采用大功率电火花震源,对规划场址区的基岩面分布情况进行走航式探测。对地震数据分析、处理、解释,成功获取了某场址区的基岩面总体分布情况。结果表明,单道地震法在海上风电场基岩探测中具有很好的适用性、准确性和经济性。At present,the exploration of the bedrock surface of offshore wind farms mainly adopts drilling or geophysical methods.Due to the high cost and long construction duration,the number of boreholes in drilling exploration is usually limited,thus it is difficult to accurately determine the distribution of the bedrock surface.The single-channel seismic method with high power electric sparker is used to conduct navigation exploration of the bedrock distribution in the planned site area.The overall distribution conditions of the bedrock surface is successfully obtained through the analysis,processing and interpretation of the seismic data.The results show that the single-channel seismic method is of good applicability,accuracy and economy in bedrock exploration of offshore wind farms.
