摘　　要：海底堆积体(充填体)体积量算技术在航道疏浚等海洋工程成本核算以及海洋执法方面有着广泛的应用。基于高精度多波束和参量阵极浅地层测量,总结了一种高精度计算海底堆积体体积的方法:提取海底堆积物表面多波束(地形)数据以及堆积体浅地层剖面(厚度)数据,通过GIS叠加及三维分析,可获得高精度海底堆积体体积数据。该方法原理简单、易于实现且精度高,基于日照海洋调查工程数据进行了实际测量与计算,证明了方法的可行性和准确性。该方法也可应用于海底以下地层中发育的特殊充填的自然沉积体相关参数的识别与量算。Measurement of submarine accumulations(or filling bodies)is widely applied for the cost accounting of marine engineering such as channel dredging and the marine law enforcement.Herein,a method for high precision calculation of the volume of submarine accumulations is summarized based on the high precision multi-beam data and the sub-bottom profiles acquired by parametric array.By this method,high precision data of the volume of submarine accumulations can be obtained by extracting multi-beam data(reflecting the seafloor fluctuation)of the submarine accumulation surface and sub-bottom profile data(reflecting the thickness of accumulation)of the submarine accumulations,and then through superimposition and three-dimensional analysis by using the Geographic Information System(GIS).This method is simple in principle,easy to be realized and high in precision,and has been successfully applied in precisely computing the volume of the submarine accumulations in the offshore area of Rizhao City.It has been proved that this method is of feasibility and accuracy and also can be applied to identify and calculate the related parameters of the naturally filled bodies formed in the strata below the seafloor.
