| 中文摘要: |
| 高斯数值积分方法应用于非圆弧拱坝多拱梁法程序有一定难度，本文针对不同的非圆弧拱特性提出不同积分变量区间的处理方法，将3节点高斯数值积分方法推广应用在5种非圆弧拱(五心拱、抛物线拱、对数螺旋线拱、椭圆拱、双曲线拱)的拱坝多拱梁法程序中，经对比计算，精度较高。 |
| 英文摘要: |
| A method for stress-strain analysis of non-circular arch dam by means of Gauss numerical method is proposed. In this method the integration variable intervals are treated by different way according to the features of arch dam. It is successfully applied to the analysis of five kinds of arch dam with different curvature including arch with 5 centers, parabolic, logarithmic spiral, elliptic and hyperbolic. |
