二、航道宽度 (一) 确定航道宽度的方法近年来,国内外对确定进港航道宽度的研究,主要采用实船观测、船舶模拟水力试验、操船模拟装置试验、数学模拟计算、以及理论和统计计算等方法。 1、实船观测有陆测和航测两种。通常,陆测是选择代表性的港口航道,采用陆上测绘仪器,根据不同的自然条件,分别连续观测不同船型的运行方位和轨迹,绘制各测点的船位图和航迹线,统计特定条件下风流压偏角和航
Second, the width of the channel (A) determine the width of the channel In recent years, at home and abroad to determine the width of the approach port research, the main use of real ship observation, ship simulation hydraulic test, pilot simulation device, mathematical simulation, as well as theory and statistics Calculation and other methods. 1, real ship observations have two kinds of land survey and aerial survey. In general, land survey is a representative port channel. Land surveying instruments are used to continuously observe the operational positions and trajectories of different ship types according to different natural conditions. Under the conditions of wind pressure declination and navigation
