摘要
在国内外研究成果基础上,从船舶航迹特性出发,根据偏航角和制动距离两个重要参数的统计特性,建立了船撞桥偏航角分布的计算模型。通过算例和参数敏感性分析,指出影响偏航角度分布的重要因素。研究成果可为桥梁设计研究人员提供参考。
Impact angle is a key parameter which will affect the impact result of bridge piers. Yet how to determine its value has not been specified in current bridge designing codes. Impact angles of ship near a bridge is closely related with aberrancy angle. So, based on sailing characters, mathematics model is buih to show ility distribution of aberrancy ship when it collisions with bridge pier. And key influencing factors for aberrancy angle are also pointed out by numerical example and parameter sensitivity analysis. The resuh will give a reference to bridge defending design.
