基于最优化计算理论中罚函数方法及传统测量平差中零权和无限权的思想,提出一种有效的迭代算法,算法过程与经典平差计算方法相同。数值实验表明,该算法简单、可行,并且具有很快的收敛速度。作者还将该模型用在大坝变形分析中,根据地形对控制点建立不等式约束,能够探测到更真实的点位位移,较之无约束平差更合理可靠。 更多还原

【Abstract】 A new effective iterative algorithm that is similar to classical adjustment is proposed based on penalty functions and zero or infinite weight.Numerical simulation shows that this algorithm is simple and feasible and has good convergence.Then it is applied to a dam deformation monitoring control net,the inequality constraints of control points are established according to the terrain and it can be detected that the real displacement of the control points and it is more reasonable and reliable th... 更多还原
