摘要
通过论证,扩大了《混凝土拱坝设计规范》(SD145-85)中纯摩公式的适用范围,认为纯摩公式对Ⅰ、Ⅱ、Ⅲ级建筑物均适用。推导出用分项系数表达的、合理的拱坝拱座稳定分析刚体极平衡法的剪摩和纯摩极限状态方程,以及不同等级建筑物在不同设计状况下的各分项系数。
In this paper through verification, applicable scope of the pure friction formula in《Concrete Arch Dam Design Standard （SD145 - 85）》is extended and can be applied to structures of all Ⅰ,Ⅱ,Ⅲ classes. The shear friction ＆ pure friction ultimate condition equation by use of rigid block ultimate equilibrium method for reasonable analysis of arch dam abutment stability have been derived ＆ coefficients of various items for structures of different classes under different design conditions have also be calculated in the paper.
