摘要
介绍了小湾水电站双曲拱坝施工测量放样计算的原理和施工测量放样要求,通过实测大坝形体数据对采用平面多卡模板代替曲面模板的拟合误差以及由此引起的大坝形体误差进行了统计分析和最终精度评估,并提出了减小混凝土形体误差在施工测量专业可以采取的措施。
The calculating principle and the requirement of construction layout in double curve arch dam of XiaoWan hydropower station are introduced in this article. The true measurement of the dam space datas are statistical analyzed and precision evaluated finally. The true measurement of the dam space datas include the error of fitting and the error of the space of the dam which lie in the plan board take the palace of the curve board. Some methods can be done on construction layout to reduce the error of the concrete space which be advanced.
