摘要
以某碾压混凝土坝实测坝体、坝基水平位移为依据,运用有限单元法分别计算坝体和坝基水平位移,建立7~#坝段上下游向水平位移的混合模型,通过混合模型反演坝体和坝基的弹性模量。计算结果表明,实测值和拟合值接近,混合模型精度较高,可为类似工程提供参考。
Based on the measured horizontal displacement of dam and dam foundation of a roller compacted concrete dam, The horizontal displacement of dam and dam foundation is calculated by finite element method, a mixed model for the upstream and downstream horizontal displacement of the 7th of a dam is established, the elastic moduli of dam body and dam foundation are inversed by the mixed model, the calculated results show that the measured values are close to the fitting val- ues, and the accuracy of the mixed model is higher, provide reference for similar projects.
