| 摘 要： | 在某砌石双曲拱坝施工中,由于施工放样的错误,使已建拱坝坝轴线偏离了设计坝轴线,为此需要重新调整拱坝体型。根据已建成的拱冠梁上游面曲线重新确定新的曲线方程,待建部分用新的曲线方程延伸,经空间有限元的应力变形分析,认为调整后的拱坝体型可行。现已付予实施。

| Abstract: | A certain double-curved arch dam needs adjusting its shape because the dam axis is wrongly aligned on site. According to the accomplished extrados curve of crown cantilever of this dam, a new extrados curve is drawn up by 3-D finite element stress-strain analysis, and is applied in the follow-up construction. |
