摘要
全站仪尤其是高精度全站仪的出现和成熟,使得道路平纵面测设出现了一种先进的测设方法——三维坐标放线法。用该法测设时,首先沿路线方向布设附合或闭合导线,同时进行基平测量;然后根据导线点进行道路中桩测设,同时进行中平测量。这样,道路纵断面测量就不必单独进行。
With the appearance and development of the totalstation, especially the one′s with high accuracy, an advanced method three dimensional coordinate method is used to survey the plane and longtitudinal view of roads.According to this way, the first locate the following line or closed line along the direction of the road, at the same time, the surveys of the base point are done.The sec ond ,the surveys of the road′s middle pile are measured in line with the line′s points then the surveys of horizonal middle line are done at the same time.So, the surveys of road′s longtitudinal view need not be done alone, therefore, the surveys done in the open can be simplied greatly.
