基于拱坝全调整拱梁分载法的基本原理，导出了材料非线性条件下的拱梁刚度方程，给出了裂缝扩展的判别与跟踪方法，并在分载法框架下研究裂缝对拱、梁应力应变的影响，形成了非线性全调整分载法．算例表明文中所述方法可行，计算结果合理．该成果可模拟拱坝在超载或材料缺陷条件下的非线性变形、开裂、裂缝扩展直至压碎破坏的全过程，可用于评估拟建和已建拱坝的安全度．
Based on the basic principle of fully adjusting arch beam loading method of arch dam, the stiffness equation of arch beam under material nonlinear condition is deduced. The method of discriminating and tracking crack propagation is given. And the influence of fractures on arch, Beam stress and strain effects, forming a fully adjustable nonlinear load-sharing method. The example shows that the method described in this paper is feasible and the calculation result is reasonable. The results can simulate the arch dam under the conditions of overloading or material defects of non-linear deformation, cracking, crack propagation until crushing failure of the whole process can be used to assess the safety of the proposed and built arch dam.
