[Abstract]:On the basis of systematically summing up and summing up the relevant research results at home and abroad, from the point of view of traffic engineering, through the collection and analysis of a large number of inland waterway (section) and lock operation data and data, the important characteristics and index parameters of inland river ship traffic (flow) are obtained. Based on the concept of traffic and transportation service quality, the research on the passing capacity and service level of shiplock is systematically carried out, and the calculation method and formula of shiplock passing capacity and service level are put forward, which can continuously and dynamically reflect the influence of ship size and standardization trend. at the same time, the calculation of shiplock passing capacity is improved from "quantity-oriented" to "quantity-quality combination" to plan and design for shiplock engineering. A new method is provided for the calculation of economic benefits. In this paper, the important characteristics and index parameters of inland river ship traffic (flow) are obtained. Based on a large number of data and data, the functional relationship between tonnage and area of inland waterway ships is established, the characteristics and measurement indexes of large and standardized inland waterway ships are discussed, the temporal and spatial distribution characteristics of inland waterway ship flow are studied, the probability and statistical distribution law of inland waterway ship flow is studied by using probability theory and mathematical statistics method, and the estimation of distribution parameters and the selection of sample capacity are discussed. The Gl/G/1 queuing model and approximate solution are used to study the ship waiting time when the busy shiplock is in normal operation in China. In this paper, the calculation method and formula of shiplock passing capacity are studied and put forward. It is clear that the unidirectional single stage single pass time of continuous multistage shiplock is independent of the series of shiplock, points out the omissions of some formulas in JTJ305-2001, establishes the calculation formula of average tonnage of primary sluice based on the relationship between tonnage and area of inland waterway ship, and puts forward the calculation method and formula of gross load tonnage and cargo (passenger) capacity of ship passing through lock. It can continuously and dynamically reflect the influence of the trend of ship size and standardization, and improve the calculation of shiplock passing capacity from "quantity-oriented" to "quantity-quality combination". In this paper, the theory of lock service level is studied and established, and the definition, division standard, evaluation index and calculation method of lock service level, engineering application and so on are systematically expounded. This paper defines the service level of shiplock, discusses and determines the classification standard of shiplock service level, deeply studies the evaluation index and calculation method of shiplock service level, clarifies the physical meaning of design service level and operation service level, puts forward the suggested value of shiplock service level division based on a large number of practical data, and discusses the engineering application of shiplock service level theory. It provides a new way for the calculation of economic benefit of shiplock engineering.
