摘要

摘要: 根据实际的地基水平约束-u的关系,提出一种非线性约束模型,并联合采用增维精细积分法和松弛迭代法获得非线性约束地基上混凝土板温度正应力和剪应力沿各横截面的分布规律。算例结果表明,该方法计算结果相当精确。

Abstract: A nonlinear constraint model is put forward according to a practical foundation horizontal constraint S- u curve. The distribution laws of normal thermal stress and shear stress for a concrete plate along its different cross- sections on a nonlinear constraint foundation are obtained by means of an incremen-t dimensional precise integration method and a relaxed iteration method.The results of a calculation case show that the method mentioned above is more effective and its calculations are more accurate.
