| 摘 要： | 回顾土体大变形固结理论的历史发展进程，从基本理论和模型试验2个方面对土体大变形固结理论研究成果进行综述。大变形固结理论的提出在一定程度上弥补了传统小变形固结理论的不足，但由于大变形固结问题的强非线性性质，其求解十分复杂。在数值分析方面，有限单元法获得了广泛应用，但基于不同参考构型描述的大变形固结问题所得到的有限元计算结果依旧存在差异。归纳总结了土体大变形固结理论的主要研究方法和最新研究成果，该研究目前存在的主要问题，并对今后可能的发展方向进行展望。 |

| Abstract： | The paper reviews the development of large strain consolidation theory of soil mass, and summarizes the research results of the theory from two aspects including fundamental theory and model experiment. The large strain consolidation theory is oversimplified for many situations, and small strain theory is only partly satisfied. Due to the complexity of the large strain theory, people normally need to use numerical methods to get the solution. With the development of the modern technology, finite element method (FEM) is widely used. But because the different methodologies were used in FEM, the solutions for large strain still show the difference. This review paper presents an overview of the theoretical developments and salient findings of large strain theory. At last, this paper also gives the future works which can be done in the future in the large strain theory area. |
