| 摘 要： | 现行交叉口立面设计大都采用手工计算的方法 ,不仅工作量大 ,而且很难判断立面设计的优劣 .笔者将交叉口设计视为曲面的设计 ,利用双三次曲面函数 ,可在极短的时间内得到该交叉口的等高线图 ,并可通过插值求得任意坐标点的标高 .设计者可适时进行调整 ,直到满意为止 .这种方法快速、方便、设计效果较好

| Abstract: | The bulk of time and effort go to design high-level profile of intersection by using existing method. Regarding the design of intersection as that of curved surface, the paper introduces a new method which can draw out quickly contour line of intersection by using the COONS curved-surface function, and gain the elevation of randorn station. The designer can adjust simultaneously the design process and reach an ideal result. This design method is very fast, convenient and efficacious. |
