张河湾抽水蓄能电站上水库施工测量技术

Construction Survey Technology for Upper Reservoir of Zhanghewan Pumped Storage Power Station

根据工程实践,提出了用全站仪直接测量平距、高差来代替测斜距、天顶距作四等及四等以下控制网测量的理论依据和方法,并以张河湾抽水蓄能电站施工控制网为例进行了比较计算.讨论了多线型、多曲面复杂形体的施工放样和计量方法.

According to the engineering practice, the theoretical basis and method that survey directly the horizontal distance and height difference by the total station system as fourth grade and below fourth grade control network are put forward instead of surveying slant distance and zenith distance. Taking the control network of Zhanghewan Pumped Storage Power Station for example, the comparative calculation is made; and the construction setting-out and measurement method for the complex form and structure with multi-line type and multi-curved surface is discussed.
