【摘要】 随时城市的快速发展,基坑工程受到人们越来越多的关注,其中如何预测基坑开挖对周围环境的影响显得最为突出。摩尔库仑模型和土体硬化模型是分析岩土工程问题的两种常用模型,均可以用于预测基坑开挖过程中周围土体的位移情况。通过建模分析与工程实测数据的对比,发现不排水条件下摩尔库仑模型和土体硬化模型[1]能在一定程度上反应基坑开挖阶段的土体变形情况,但并不是十分准确。在实际运用中,这两种模型的分析结果只能作为预测基坑整体变形的参考数据。更多还原

【Abstract】 With the development of the city, the objective of deep excavation is become one of the most important points in our lives. People pay more and more attention to how to predict the deformation of deep excavation. The Mohr- Coulomb model and the Hardening- Soil model are two commonly used models for analysis of deep excavation under the undrained condition, they can both predict the deformation of deep excavation. By comparison with the field test data, it is found that both of those two models can’t give the accurate result about the deformation. So those models can only be used as reference for the deformation prediction of deep excavation.更多还原
