摘要
通过对比分析目前国内外应用较多的AASHTO规范模型、欧洲规范模型、KUNZ模型和黄平明直航路模型等船桥碰撞概率计算模型的优缺点,提出三概率参数积分路径模型,同时考虑了三峡库区高水位落差的影响。通过对库区3座跨江大桥的航迹线进行实际观测,获得了三概率参数积分路径模型中所需的航迹横向分布和偏航角度分布,并运用该模型进行实例分析。
By comparing and analyzing the advantages and disadvantages of probability calculation models for bridge crashed by vessels such as ASSHTO normative model, European normative model, KUNZ model and Huang-ping-ming straight waterway model often applied at home and abroad, this paper proposes three probability parameter integral path model and takes the influence of high water level fall in Three Gorge area into account at the same time. By practical observation of course of three cross-river bridges in Three Gorge area, the paper acquires the lateral distribution of course and angle distribution of deviation required by three probability parameter integral path model and makes example analysis by means of this model.
