带激光反射镜重要设备轴线方位角测量方法的探讨

The Discussion of Important Equipment Axis Azimuth Measuring Methods with Laser Mirror Reflection

随着我国国民经济的快速发展,各项重大工程项目不断开展,测量在工程项目建设的地位重要性越来越强,经常会遇到很多涉及到重要工程的高精度测量,特别是受工程与项目环境的约束,采用常规的作业方法受到局限,如何采用最优最可靠的方法是测绘服务国民经济需要研究的问题,在可重复验证满足测量精度的同时,需要对独立的工程项目进行专项测量技术设计,以此来满足工程独特的技术与精度要求;本文探讨对某重要激光反射设备进行激光反射镜反射的不可见短轴轴线方位进行测量,由于受设备环境影响,激光镜面可见,垂直镜面反射的激光轴线在设备内不可见也不可延长,如何高精度的测量激光轴线方位是设备安装后调试的关键。

With the rapid development of national economy and important construction project, the surveying becomes much more important in the construction projects. In the meantime,a high accurate surveying is required in many important projects. There are also a number of problems, such as constraints of project environment, limitation of convention- al method and so on. Then how to adopt optimal and reliable methods in surveying and mapping projects becomes a significant research field. For those proiects, it is convinced that the design of special surveying technology should be used in independent projects to meet the demand of unique technology and accuracy. This paper discusses some important laser reflection equipments which can be used to survey the non--visible short axis orienta tion surveying with laser mirror reflection. Under the effects of the equipment environ ment, the laser mirror is visible. By contrast, the vertical mirror reflection of the axis of the laser cannot be seen or prolonged. Therefore, how to set a high accuracy of measuring la- ser axis orientation becomes a key point in debugging after the installment of the equipment.
