摘要:
为研究内河船闸通过能力,对其关键参量一次过闸平均吨位的计算方法进行改进,建立了基于船舶吨位与面积关系的一次过闸平均吨位计算模型.结合实测资料,对模型的船舶吨位与面积关系以及闸室利用率进行了分析.船舶吨位与面积关系可采用线性、二次多项式等函数进行回归分析得到,闸室利用率可采用其年平均值,一般在0.5~0.7之间.验证表明:该模型结构简单,能够得到令人满意的结果; 较之规范(JTJ305—2001)推荐的方法,回避了过闸设计船型的选取及其组合等不确定性因素,能够动态地反映船舶大型化和标准化趋势的影响,根据实际或预测的船舶平均吨位即可连续计算一次过闸平均吨位,为船闸通过能力计算提供了新思路.
Abstract:
In order to research the lock capacity, an analytical model is developed for the average lockage tonnage(ALT)at a waterway lock based on the relationship between the tonnage and area(RTA)of inland vessels, and the percent of available chamber(PAC). According to the field data, RTA can be described with a linear equation, or a quadratic polynomial, and the annual average value of PAC is about 0.5-0.7. The validation shows that this simple model can obtain a satisfied result. Compared with the method recommended by the code(JTJ305—2001), this model avoids the uncertain factors like design vessels’ selection and their combinations, and can dynamically reflect the effect of the large and normative vessels on lock capacity. According to the actual or forecasted average tonnage, ALT can be determined with RTA and PAC. This study provides a new thought for the calculation of lock capacity.
