全站仪自由设站法的探讨与应用
|
摘要
目的在使用全站仪进行施工测量的过程中,往往会因为建筑材料的堆放或因地形复杂等不可改变之因素,造成测站之间无法相互通视,或通视困难造成测量不精确、数据不可靠。方法浅析了全站仪自由设站法在具体工程实例中的应用,介绍了控制点及监测点布设方案,对自由设站进行精度分析,判定测量数据的可靠性。结果全站仪自由设站法以其实测自由度大、精度高、测得数据可靠等优点避免了测站之间相互通视困难的问题。结论全站仪自由设站法精度高,复杂地形下测量自由度大,在实际施工测量活动中具有推广意义。
Objective In the process of construction measurement by the use of total station,it is often because of the pile-up of building materials or the irreversible factors such as complex terrain that the surveying stations can not see each other,or there is difficulty of seeing each other,which results in inaccurate surveying and unreliable data.Methods Briefly analyses the application in specific engineering examples,introduces the layout scheme of control points and monitoring points,carries out precision analysis of free station,and determines the reliability of measured data.Results The free station setting method of total station avoids the difficulty of communication between stations because of its advantages of large degree of freedom,high accuracy and reliable measured data.Conculsion The results show that the method of free station-setting with total station has high precision and large measurement freedom under complex terrain.It is of great significance to popularize in practical construction survey activities.
