摘要
目前在工程测量中,全站仪已得到了广泛的应用,基于全站仪在工程放样应用中要求测站点与待放样点必须通视,而在实际工作中这两点常常是不通视的,提出了一种新的全站仪放样方法,详细论述了放样原理、精度以及可靠性,并依托大唐桂冠合山发电有限公司2×600 MW级机组上大压小工程主厂房桩基A标工程项目,论证了该方法放样结果的内符合与外符合精度。实践证明,该放样方法在不同精度要求的工程中是可行的、可靠的。
Currently in engineering surveying, electronic tachometer has been widely used, based on electronic tachometer lofting applications in engineering requirements for lofting points with measurement site must pass visual, however, in the actual work of these two points are often impassability visual. Therefore, this paper presents a new electronic tachometer lofting method, and a detailed discussion on the lofting principle, accuracy and reliability. At the same time, this paper based on the Datang crown close mountain GongSiJi units on the big power limited pressure small project main workshop of pile foundation A standard engineering projects, demonstrates the method of lofting results within and outside precision. It has been found that, this paper expounds the lofting method in different accuracy requirements engineering is feasible and reliable.
