摘要
高程测量在工程建设中具有重要作用,常见的几种高程测量方法有GNSS高程测量、水准测量与三角高程测量,首先简要介绍几种高程测量方法,并对水准测量与三角高程测量的误差源简要分析,然后通过工程实例对几种高程测量方法进行精度对比,为实际工作中选择最佳测量方案提供理论支撑。
Height surveying plays an important role in engineering construction.Several common height surveying methods include GNSS height surveying,level height surveying,and triangulated height surveying.First,several height surveying methods are briefly introduced,and the error sources of leveling and triangulated height surveying are briefly analyzed.Then,an engineering example is used to compare the accuracy of several elevation-survey methods to provide theoretical support for selecting the best surveying scheme in actual work.
