距离趋近法确定测点与线路的相对关系

在工程设计、施工及竣工阶段,经常需要测定点与线路中线的位置关系,以便为设计、施工及竣工提供准确数据。但用传统方法计算测点与线路中线的位置关系公式复杂、难度大,针对这一问题从工程测量的实际出发,用坐标与方位角表示点到直线的距离,运用曲线计算的统一模型,提出距离趋近法原理,快速确定测点与线路的相对关系。不仅解决了常规方法难以解算的问题,又保证了计算的精度,对工程应用具有实际的意义。

The relationship between measuring points and line determined by distance approaching

In order to provide accurate data for the stage of engineering design, construction and completion, it always measures the relationship between the points and middle line. With the traditional method to measure the relationship between points and middle line, the formula is too complex and difficult. The paper based on the reality of the engineering, by corrdinating and azimuth represents a point to straight line distance, using curves unified model, proposed the distance approaching to determine the relativity of points and lines quickly. The method not only solves the problems that is difficult for convention method, but also ensures the accuracy of the calculation. The method has great practical significance.
