In this paper , an approach of the systematic artificial neutral net was introduced into the analysis on the ship - against - bridges probability with a computer programs . based on the basic data of the present 12 typical bridges as the sample , 4 chief influential factors as the input coefficient , such as the bridge span , the water flow rate , the incline angle between water flow direction and the direction normal to bridge axis , and the curve in the course near the bridge area , with the ship - against - bridge probability as the output coefficient , the intelligent judging system of the ship - against - bridges probability reflecting the influence of the above input parameters is obtained after training
本文首次将人工神经网络系统方法引入了船撞桥概率的研究当中，编制了计算程序，成功地以现有12座典型桥梁的基础数据为样本，以桥梁跨径、水流流速、水流方向与桥轴法线的夹角以及桥区航道弯曲度等4个船撞桥主要影响因素为输入参数，以船撞桥概率为输出参数，经训练得到了能较好地反映上述输入参数影响的船撞桥概率判断系统。
