水泥混凝土路面板厚计算中温度应力系数B_x的数解法

Methematics Analysis Method of Temperature Stress Coefficient B_x on Calculation of Board Thickness of Cement Concrete Pavement

在水泥混凝土路面设计中 ,水泥混凝土板的温度应力系数 Bx 是在规范中人工查图确定的 ,这会带来较大的人为因素的影响 ,造成设计结果的不唯一性 ;同时也不便于计算机程序化的实现 ,提高设计的效率。本文对图形采用回归方法拟合出求解温度应力系数 (Bx)的数学方程 。

As the temperature stress coefficienton B x in th e board thickness design of cement concrete pavement is artificially got from th e standard plot usually, it not only makes different results with different desi gne rs but also makes it is difficult to realize design automatization The paper ha s got methematics equation to solve temperature stess coefficient B x by c urvilinear regression method and makes it easy to write program and reali ze design automatization
