浅议三角板高程放样法及应用

Elevation Lofting Method of Triangular Plate and Its Application

“三角板”高程放样方法很好地解决了用传统及现代测量方法无法快速放样高精度高程的缺点,利用三点一线原理在两基准点间任意位置加密高程,减少了用普通水准仪及三角高程等测量方法进行加密高程点时必须通过距离、角度和高差等直接观测进行高程计算的程序,其在工程中的推广和成功应用,加快了施工进度,提高了工程质量并取得良好的经济及社会效益。

The method of “triangle plate” elevation lofting solves the shortcoming that traditional and modern measuring methods can't quickly lofting high-precision elevation,it uses the principle of three points and one line to encrypt elevation at any position between two datum points,and reduces the need for direct observation such as distance,angle and elevation difference when using ordinary leveling and triangle elevation measurement methods to encrypt elevation points. The popularization and successful application of the program in engineering have accelerated the construction progress,improved the quality of the project and achieved good economic and social benefits.
