摘　　要：为探明海底地质断层深度和形状,本文利用层析术探测一定海区面积范围内海底介质中具有不平整曲面形态的断面深度和形状,给出了接收阵布设原则与解算公式。该方法的优点是分析公式与计算方法简单,并可以一次性测定较大面积海区范围内海底断层的情况,其不足在于要借助事先的环境建模,并且不适用于对断崖式断面测定。In order to determine the form and depth of fault in sea bottom.The exploration of non-regular curved fault within certain finite sea area had been given by means of tomography.In paper the principle of bottom sonar location and formulae for data processing are given.The advantage of this method lies in that,it will more easier for analysis and computation,and can perform at same time the exploration within certain sea area.But it depends on suitable modeling and will not fit for measurement of fault,having the type of cliff.
