| 摘 要： | 运用FLAC3D软件中的Mohr-Coulomb本构模型对北京市某高层住宅楼基坑工程进行了数值模拟分析，对基坑开挖、失稳破坏、边坡支护进行了评价，并对模拟结果与实测结果进行了对比，分析了基坑变形、失稳破坏和支护过程。研究表明，FLAC3D软件中的Mohr-Coulomb本构模型能够方便、准确地模拟基坑开挖、边坡的大位移失稳破坏、边坡的支护过程，其计算结果安全可靠。分析结果也证实了FLAC3D在基坑工程数值模拟方面具有良好的适应性。

| Abstract: | The simulative analysis with the Mohr-Coulomb model of FLAC3D program is carried out based on the development of deformation for foundation pits of a high-rise building in Beijing. Comparing with the results of the in-situ monitoring, the deformation, collapse and support for the foundation pits are discussed. It can be shown that the Mohr-Coulomb model of the FLAC3D program can be used to simulate the foundation excavation and the collapse and the slope support very conveniently and accurately. The results obtained are safe and reliable. The FLAC3D program can be widely used in the simulation of foundation pits. |
