摘要
将规范计算混凝土坝体应力进一步细化,通过对坝体应力函数采用变步长网格法编程计算,计算了各节点的主应力和最大剪应力,并采用样条插值实现了应力等值线的简化计算,同时也给出了应力迹线的分布,为设计人员提供更为简单、直观的应力场。
Based on further details of calculation of the stress in a concrete gravity dam in accordance with standard, the principal and maximum shearing stresses of each node in the dam are calculated from the stress function by a program of grid method of the changed step length. The simple calculation for stress isolines is brought about by a spline interpolation method, as well as the distributions of stress trace are given, which can provide more simple and direct stress field for designers.
