摘要
根据黏弹性有限元反分析理论,在地下工程软岩流变问题中引入西原模型,探索了黏弹性有限元反分析方法,并进行参数优化、可靠性分析和计算精度对比,通过工程实例计算,论证了该方法的可行性和可靠性.
Based on the theory of viscoelastic finite element back analysis in underground engineering, Xiyuan finite element model was introduced in the problem of soft rock rheology, and viscoelastic finite element back analysis method was developed and parameters optimum, reliability analysis and precision comparison were executed. Feasibility and reliability were verified by calculating a practical engineering.
