摘　　要：结合郑州某基坑支护实例,运用FLAC3D程序对该工程的基坑开挖过程进行模拟,建立了三维数值模型,对基坑支护的全过程进行了分步模拟.模拟结果表明,开挖支护后基坑从整体上是稳定的,与施工结果基本相符.According to the foundation excavation supporting example in Zhengzhou city, an analysis with FLAC3D was carried out on the process of construction, establishing the three dimensional numerical model. The step-simulation of the retaining and protecting for foundation excavation was carried out. The analogue result indicated that the building foundation pit is stable after excavation and identical with the construction resuit.
