本文以试载法为基础,提出拱坝应力分析的分载位移法.本法以拱单元和梁单元为计算体系,按位移法分别由拱和梁两套系统建立以结点变位和分配荷载为未知量的平衡方程,从中消去分配荷载得到以结点变位为未知量的整体协调方程.与常规试载法比较,本法具有计算工作规格化、内存少、计算量小及便于动力分析等优点.
Based on the trial loading method, this paper proposes a load-displacement method for stress analysis of arch dams. This method uses arch units and beam units as the calculation system. Displacement and distribution of joints are established by the displacement and arch systems respectively. The load is the balance equation of unknown quantity, from which the distributed load is eliminated and the overall coordination equation with the node displacement as unknown is obtained. Compared with the conventional trial load method, this method has the following features: normalized calculation work, less memory, less calculation, and easy power. Analysis and other advantages.
