摘要
根据岩土材料的室内蠕变试验结果，提出了一种理论模型和用于数值分析的计算公式，并对上海地铁一深基坑开挖工程进行有限元分析。
A nonlinear creep soil model which is based on laboratory creep test results is proposed in the present paper. Finite element analysis for this nonlinear creep soil model is developed and numerical analsis is carried out for a deep excavation project. The measured results compare favourably with the numerical results which suggests that this new model can be used for practical case.
