摘要
针对某碾压混凝土重力坝引水系统下平段厂坝分缝处坝体应力与变形问题,提出了三种灌浆方案并构建了坝下游面钢衬钢筋混凝土管的整体有限元模型,在线弹性假定条件下分析了每种灌浆方案五个计算工况时厂坝分缝处大坝应力应变规律,经优化最终选择方案Ⅱ效果最佳。
Aiming at the stress and strain of dam and plant parting in bottom flat placement segment of diversion system for a certain RCC gravity dam,three grouting schemes are proposed and the whole finite element model of steel lined reinforced concrete pipe in downstream dam is established.Under the condition of linerly elastic hypothesis,it analyzes the stress and strain laws of dam and plant parting with five calculation conditions for each grouting scheme.The second scheme is selected by principle of optimality and it has the best effect.
