摘要
以锦屏一级双曲拱坝为例,介绍双曲拱坝形体控制测量和施工测量方法;通过对锦屏一级大坝每层曲率最大处采用平面多卡模板代替曲面的拟合误差的理论计算,证明平面模板代替曲面对大坝形体的影响超出规范的要求,提出在施工测量过程中采取折中的处理措施;利用可靠的检测数据和测量精度估算证实,采用折中的测量处理方法对提高大坝形体质量是有效的。
With the damming technology,application of super high arch dam is increasing gradually,the appearance of more and more high quality requirements.In this paper,a class of hyperbolic arch dam in Jinping first stage as an example,introduces the hyperbolic arch dam body control survey and construction survey calculation method;fitting error through the Jinping first stage dam every maximal curvature of the plane of Doka formwork instead of surface theory,proved that the planar template instead of curved face of dam body beyond the specification requirements,put forward the measures in the construction process of compromise measure;the test data and the measurement accuracy estimation of justice confirmed by measuring the processing method of compromise is effective to improve the quality of dam body.
