堆石坝混凝土面板干缩应力的研究
Research on drying shrinkage stresses of concrete slabs on rock-fill dams
【摘要】 本文研究堆石坝混凝土面板湿度场和干缩应力的理论解 ,并通过一些算例研究混凝土面板的湿度场和干缩应力的发展规律 ,提出预防面板产生干缩裂缝的措施。
【Abstract】 Some theoretical solutions of moisture field and drying shrinkage stresses of concrete slabs on rock-fill dams are presented in this paper. The regularity of shrinkage stresses is analyzed with some computational examples, and some measures to prevent shrinkage cracks are recommended.
