多浅段航道设计通过能力仿真

Design throughput capacity simulation for multi-shallow waterway

为合理评估多浅段航道设计通过能力及确定航道疏浚量,改进了对传统多浅段航道乘潮方式的计算方法,应用离散事件仿真方法对航道通航条件及影响因素建立航道设计通过能力的计算模型,并根据国内某航道的实际资料进行仿真计算.结果表明,针对多浅段航道的各浅段分别进行建模和疏浚方案设计的模拟计算,可以在保证航道通过能力的情况下仅对个别浅段进行疏浚,大大降低了航道的疏浚成本;同时,对多种疏浚方案进行比较计算,可以确定较优的疏浚深度,对航道建设规模确定有重要的理论价值和实际意义.

To reasonably evaluate the design throughput capacity of multi-shallow waterway,while determining the amount of dredging,the traditional tidal mode calculating method for multi-shallow waterway was improved,and discrete event simulation was adopted to establish throughput capacity calculation model for both the channel navigation conditions and the influencing factors.Simulation was carried out according to the actual data of a domestic channel.Results show that the model established for each shallow of multi-shallow waterway and simulation calculation for designed dredging scheme can make waterway dredging only for individual shallow while ensuring throughput capacity,which can greatly reduce the waterway dredging costs.Meanwhile,various dredging schemes were compared so as to determine the optimal depth of dredging,which has important theoretical and practical significance for waterway construction.
