随着测距技术的发展,各种测距仪、全站仪在导线测量中得到了广泛应用。在实际作业中,如果依据的控制点成果精度低,同时又不大注意测距仪器的使用,则施测结果常达不到测量规范相应等级的精度要求,造成不良后果,轻则返工、延误工期;重则给人民的生命、财产造成重大损失。因此,如何正确使用这些先进的仪器,熟练掌握导线测量的方法和措施,一次性达到测距导线测量成果的精度要求,是本文讨论的重点问题。结合实践现状,分析测距导线闭合差超限原因及应采取的主要措施,严格按照测量规范要求作业,实现导线测量的一次性成功。
With the development of ranging technology, various range finders and total stations have been widely used in wire measurement. In actual operation, if the accuracy of the results of the control points based on low, while not paying attention to the use of ranging instruments, the measurement results often fail to meet the appropriate level of measurement specifications accuracy requirements, resulting in adverse consequences, ranging from rework, delay Duration; weight gives the people’s lives, property caused heavy losses. Therefore, how to correctly use these advanced instruments, master the methods and measures of the wire measurement, and meet the accuracy requirements of the measurement results of the wire once and for all is the key issue discussed in this article. Combined with the actuality of the situation, this paper analyzes the causes of the overrun of the distance between the lead wires and the main measures to be taken, and operates in strict accordance with the requirements of the measurement standards to achieve a one-time success of the wire measurement.
