| Abstract: | 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. |
