摘要
针对混凝土早期水化热引起的裂缝危害性,从变分原理的角度出发,建立并证明了混凝土板早期水化热温升的一维导热方程的泛函形式,用Ritz法求出了该导热方程的近似解。
In light of the crack caused by concrete's early hydration heat, the author sets up .and proves one-dimensional heat conduction equation's functional form of concrete slab's early hydration heat temperature rise.started from the angle of variational principle, and solves the equation's approximation by using Ritz method.
