A Study On The Relationship Of Inland Waters Channel Dimensions And Navigation Capacity

With the rapid development of China's economy, inland shipping industry is gradually recovering and prosperous. However, while inland shipping industry in driving and promoting China's rapid economic development, it has encountered with some pressing problems. On one hand, a number of newly-constructed hydraulic constructions along piers, bridges and ports have flourished like mushrooms in the spring. As the change of navigation channel environment, the passage ability of inland channel has changed. On the other hand, the rapid development of inland ships of larger scale, modernized and specialized requires higher navigation environment standards. The navigation dimensions conflict with the existing passage ability of navigation channels.Therefore, in order to make sure the larger vessel can pass and the channel resource be fully used in a limited water area and channel in a certain scale; to ensure the safety of vessel especially big vessel shipping in a channel, prevent stranded or sunken accidents for blindly and blocked channel incidents; to facilitate maritime department organization and management and shipping companies productive sector dispatch more reasonable; to help Channel management organizations control channel information reasonable and provide the basis for development of channel construction, maintenance and plans, analysis of the relationship between inland waterway channel scale and Navigable capacity is very necessary and urgent.In order to study the relationship between the channel navigation capacity and ship size, the existing river channel is divided into straight paths, curved paths, bridge area waterways and other typical channel, analyzing the size of existing flight typical channel and its variation, according to theory of ship handling and pilot theory, and fully consider the role of romantic characteristics of the ship, with reference to the relevant norms and standards, analyze the relationship between channel depth, flight width, curvature radius, clearance height of the ship navigation channel scale and ship size, building relational mode between the scale and channel-scale ship by mathematical modeling method to calculate the shipping channel capacity, calculate shipping channel capacity by programming and explore application software. Finally, on the basis of inland pilot age technology and inland channel theories, the thesis explores the information forecast methods and schemes to realize typical inland channel capacity for large scale ships by computer programming.
