航道疏浚中挖槽设计与工程计算

Channel Design and Engineering Calculation in Waterway Dredging

文章以航道测量数据为基础,介绍了采用多层叠加面法拟合航道河床地形曲面的方法以及将该方法应用于航道挖槽中线确定、尺寸设计和土方量计算。实践结果表明:用该方法所开发的挖槽设计系统,提高了计算精度,缩短了设计时间。

The function of waterway bottom terrain surface is formed based on the survey points by method of multi-layer curve surface congruence, which is used to decide channel mid-line of waterway, to design channel dimensions and to figure out dredging volume. The channel design system is developed with the idea and method mentioned above,which are useful in processing design data. It has improved calculation precision and shortened design period.
