| 摘 要： | 用三点抛物线法计算的中轴线与直线的交点坐标与解非线性方程计算结果基本相同,其精度可满足施工精度要求。该方法计算比较简便,因此,在拉西瓦拱坝的横缝设计中采用了三点抛物线法计算横缝坐标。

| Abstract: | The intersection coordinates of central axis and straight line are computed by the three-point parabolic method,which is basically in accordance with the results computed by the nonlinear equation,and its accuracy can satisfy construction requirements.The method is easy to use,and is adopted to calculate transverse-joint coordinates in the design of transverse joint for Laxiwa double curvature arch dam. |
