Abstract:

Traverse survey has the advantages of easy setting, convenient measuring points selection, and is flexible especially in the situation of too many buildings and poor sighting condition. The principle of condition adjustment and the solution method of closed traverse condition adjustment are introduced. Taking Xianyou Pumped Storage Power Station as an example, the traverse at the entrance of the division tunnel of upper reservoir was increased. By using the principle of condition adjustment of traverse, the program was designed and compiled under Visual FoxPro, and the condition adjustment of closed traverse was realized. The check of practical project proved that the method has high accuracy, which can meet the requirement of project construction with strong practicability.

Key words: closed traverse, condition adjustment, calculation method
