| 摘 要： | 分别采用拱梁分载法(四向调整)和三维有限元法对石膏山混凝土拱坝进行了5种工况的应力计算分析。根据计算结果提出坝体封拱灌浆分三个区域:坝体高程1 119.0 m以下为一区,封拱温度为14.3℃;坝体高程1 119.0～1 130.0 m为二区,封拱温度为12℃;坝体高程1 130.0 m以上为三区,封拱温度为6.5℃。

| Abstract: | Based on arch-cantilever method and 3D finite element method,the stress of Shigaoshan concrete arch dam was analyzed under 5 conditions.According to the calculation results,the dam body is divided into 3 zones on the basis of closing arch for grouting: the dam body under the elevation of 1119.0m is zone 1,the joint closure temperature is 14.3℃;the elevation of the dam body between 1119.0 to1130.0 meters was zone 2,the joint closure temperature is 12℃;the dam body above the elevation 1130.0m is zone 3,the joint closure temperature is 6.5℃. |
