随着时代的进步,科学技术的不断发展,测量工程与测量仪器工具也在不断的更新和改进,促使施工放样工作越来越简化,精度也越来越高。人们可以根据需要采用不同的放样方式。对一些放样点数少,又有相关地物点能保证精度的,可采用传统的方法。对于精度要求高的,如贯通工程、桥梁等要采用全站仪结合水准仪进行坐标和高程放样。本文主要探讨几种常用的工程放样基本方法。 With the progress of the times and the continuous development of science and technology, the measurement engineering and measuring instrument tools are constantly being updated and improved, which has led to the streamlining of construction setting-out work and the increasing precision. People can use different lofting methods as needed. For some of the fewer points, but also related to the point of things to ensure accuracy, the traditional method can be used. For the high precision, such as through engineering, bridges and other stations to be combined with the level of coordinates and elevation lofting. This article mainly discusses several commonly used basic methods of project lofting.
