预测海洋沉积物中声波速度和衰减的一种有前途的方法是使用Stoll实施的毕奥理论。在这里，在现场应用的Biot-Stoll物理沉积模型进行了检查。在地中海的三个浅水站点测量了地球物理输入和地声输出。这使得调查的准确性模型的各种天然海洋沉积物，包括粉质粘土，沙子，砾石。使用Biot-Stoll模型的一个困难是准确确定13个地球物理输入的问题，因为许多输入无法直接测量。其中10个输入属性是通过经验方法得出的，另外3个属性是通过测量确定的。在现场和实验室测量的纵波速度，纵波衰减和横波速度的Biot-Stoll模型预测之间的比较。模型预测，总体上，表现出色…
A promising approach in the prediction of acoustic wave speeds and attenuations in marine sediments is the use of the Biot theory as implemented by Stoll. The Biot–Stoll physical sediment model is examined here in a field application. Both the geophysical inputs and the geoacoustic outputs were measured at three shallow‐water sites in the Mediterranean Sea. This permitted the investigation of the accuracy of the model for a variety of natural marine sediments including silty clay, sand, and gravel. A difficulty in the use of the Biot–Stoll model is the problem of accurately determining the 13 geophysical inputs since many of the inputs cannot be directly measured. Ten of the input properties are derived by empirical means and the other three properties are determined by measurement. Comparisons are made between the Biot–Stoll model predictions of compressional velocity, compressional attenuation, and shear velocity with in situ and laboratory measurements. The model predictions, on the whole, show excelle...
