摘要
利用全站仪的坐标测量、高程测量、对边测量以及坐标放样等功能,推导出了利用坐标法进行路堑开挖线放样的数学模型,将这项放样由传统的中线设站逐点逼近法改进为任意点设站坐标逐点逼近法。并将放样过程中繁杂的计算交由PC-E500S程序或CASIO可编程计算器程序完成,使路堑开挖线的放样方法更加灵活多样,放样效率和定位精度得到显著提高。
Some functions, i.e. laying-out of coordinates, elevation, subtense and coordinates determination, can be carried out by using of total stations, in which the mathematic model of laying-out excavation cutting with coordinates method is derived. And the traditional distance-approaching method by setting-up instruments on midpoint is ameliorated to a coordinates-approaching one , in which the instruments can be set up freely. Meanwhile, The complicated computation of the laying-out procedures can be accomplished by means of PC-E500S or CASIO calculators to make the laying-out operation various and productivity improved obviously.
