In the third part, the theory of thrust angle and unbalanced forces is studied andapplied to Xiluodu arch dam. some conclusions are obtained :(1) The thrust angle issmaller by elaso-plastic computation than elastic computation. For the non-linearcomputation, the thrust angles at different elevations all increase during overloading,which reveals the internal mechanism of good performance of arch dam in conditionof overloading;(2) The elaso-plastic theory always minimizes the actual unbalancedforces in the sense of a condition number in the norm ofcomplementary energy.

第三部分，通过对溪洛渡拱坝拱端推力角及不平衡力的研究，得出如下结论：(1)非线性计算较弹性计算的推力角大；对于非线性计算而言，拱坝超载过程中各高程段的推力角均有所增加，这反映了拱坝具有较高超载能力的内在机制；(2)在总余能范数的意义上，按弹塑性本构关系确定的不平衡力或加固力是最小的，弹塑性计算确定的加固力和真解相比偏于安全。
