摘 要:针对已建的某港导标方案的设计参数为比照对象 ,在导标引导范围及前标条件不变的基础上 ,试以调整前后标距及后标高程增补 5个方案 ,并计算有关参数与之比较。比较结果表明 ,方案 5是将后标置于丘陵高点 ,可使后标减少 6m高度的建设费用 ,并使导标垂直张角及侧面灵敏度更趋于合理。因此 ,导标方案 5是较为经济合理。In comparison with the design parameters of the leading mark alternative of an as-built port and on the conditions of not changing the leading range and front leading mark conditions, 5 supplementary alternatives which try to adjust the space of the front and back leading marks and elevation of the back leading mark are provided, with relevant parameters calculated and compared. Alternative Ⅴ is to place the back mark at the highest point of the hilly area, by which not only the construction cost of 6m high mark can be saved for the back leading mark, but also the vertical flare angle and side sensativity tend to be more rational. So, Alternative Ⅴ for the leading mark, which is more economical, rational and convenient, is determined to be the optimization alternative.
