摘　　要：针对海洋地震物探船布设探测网络实际工况的要求 ,提出一种拟合数值计算与模型实验结果预报拖缆姿态及拉力的方法。应用此方法进行多方案比较研究 ,获得优化的拖缆 -扩展器 -检测电缆组合探测系统。经海上拖航实验验证 ,此种预报方法可行 ,预报精度完全能满足工程实用要求。For the arrangement of the survey network of the ocean seismic prospecting ship, a method fitting the results of the numerical calculation and the model test is presented in this paper. The state of the spreader in water and the pulling force can be predicted using this method.After comparing various plans in the application of the method, an optimum streamer spreader test cable combining system is obtained.Through the towing in practice,it is verified that the predicting method is workable and the predicting precision satisfies the engineering requirements.
