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.
