摘要
徐变对混凝土坝的应力、应变影响较大 ,文章针对沙牌碾压混凝土拱坝埋有正、倒垂线及一定数量应力应变计的特点 ,提出一种反演沙牌坝体碾压混凝土徐变度的方法 ,并研制了相应的计算程序。
Creep deformation affects the stress and strain of concrete dam. In this article, a back analysis method for the creep degree of roller compacted concrete arch dams is presented and a coupled analysis program is developed, based on characteristics of positive inverse vertical lines and stress strain metres buried in the dam body of Shapai roller compacted concrete arch dam.
