摘要
伊洛瓦底江是中国西南直达印度洋航线的重要水运通道。针对伊洛瓦底江航道尺度的开发潜力问题,基于水力学、河流动力学,参考已有航道潜能估算方法推导得出航道水深理论公式,采用实测资料和经验参数估算了伊洛瓦底江不同航段理论上能达到的航道水深。结果表明:伊洛瓦底江在通航保证率为98%条件下,八莫至曼德勒航段、曼德勒至卑谬航段、卑谬至仰光航段最小航道开发水深分别为2.14、2.58、2.75 m,年通过能力18亿t以上。研究结果可为伊洛瓦底江的航道开发提供一定的理论技术支撑。
The Irrawaddy River is an important waterway that opens the direct route from southwest China to the Indian Ocean.Aiming at the development of the Irrawaddy River waterway,this paper deduces the theoretical formula for the waterway depth based on the hydraulics,river dynamics and available estimation methods for waterway potential,and estimates the theoretical depth of the waterway that can be achieved in different sections of the Irrawaddy River by the measured data and empirical parameters.The results show that under the condition of 98%navigation guarantee rate of the Irrawaddy River,the minimum waterway development depth from Bhamo to Mandalay,Mandalay to Prome,and Prome to Yangon is 2.14 m,2.58 m and 2.75 m respectively,and the annual navigation capacity is more than 1.8 billion tons.The research results can provide some theoretical and technical support for the development of the Irrawaddy River waterway.
