摘要
本文用有限元法对加筋补强地基进行了模拟数值分析．在分析中采用了接触单元模拟土与土工织物之间的界面特性，并采用梁单元来模拟土工织物．通过对拉拨试验的模拟以及陕西某电厂灰场应急灰坝的有限元分析，证明分析方法符合实际．
The deformation and stability behaviors of a reinforced foundation are studied by FEM in this paper. The friction contact interface element is introduced to simulate the interaction of soil reinforcement. The flexible beam element is used to simulate the geotextile. The simulation method is verified by experiment and the computational result of a fly ash dam.
