摘要
长江是重要的航运通道,碍航滩段对船舶安全航行造成严重影响,以长江涪陵至丰都老虎梁河段为研究对象,基于实测的水文地形资料,采用二维水流数学模型,对典型滩段的碍航特性、整治参数、整治方案进行了研究.基于二维水流数学模型及船舶操纵模拟,对整治方案的效果进行了评估,并确定窄深型挖槽方案为最优整治方案,为消除通航瓶颈、保障船舶安全和航道畅通提供技术支撑.
Abstract
The Yangtze River was an important shipping channel,which seriously affect the safe navigation of ships in obstructing the navigation beach section.Based on measured hydrographic topographic data,the research was carried out on Laohuliang beach of Fuling to Fengdu.The navigation obstruction characteristics,regulation parameters and regulation scheme of typical beach section were studied by using two-dimensional flow mathematical model.Based on the two-dimensional flow mathematical model and ship maneuvering mathematical model,the effectiveness of the remediation plan was evaluated and the optimal remediation plan was determined.This research results can provide technical support for eliminating navigation bottlenecks,ensuring ship safety,and smooth navigation channels.
