自然高差Δh与斜面双轨中心距的关系

Relationship Between Natural Height Difference Δh and Slope Double Track Central Distance

论文通过研究《采矿工程设计手册》中关于双道起坡自然高差的计算过程,发现Δh、ΔL、ω的计算都是以双轨中心距的水平投影作为计算的基础,没有找到实际的双轨中心距和角度、线路的空间关系。而Δh又是一个很重要的中间参数,影响着高低道最大高差ΔH的计算、竖曲线半径的选择等。文章主要把Δh、ΔL、ω的计算和实际的双轨中心距建立关系,求出准确的Δh。

With the study on the calculation process of the natural height difference in the double track slope of the mining engineering design manual,the calculation of Δh、ΔL、ω was found that the horizontal projection of the double track central distance was the basis of the calculation.The space relationship between the actual double track central distance,angle and route was not found.But the Δh was a very important middle parameter affected to the calculation of the max height difference ΔH in the high and low track roadway and the selection of the vertical curve radius.With establishment of the relationship between the Δh、ΔL、ω calculation and the actual double track central distance,the Δh could be correctly calculated.The design drawing obtained would be more accurate and could be better to guide the production.
