摘要
根据数值分析相关理论,建立地下通道模型,采用FLAC3D有限差分法软件对某地下通道开挖进行数值模拟,根据数值模拟计算结果分析周边建筑是否安全,并提出地下通道开挖过程中所采取的安全措施。数值模拟计算结果反映周边建筑的沉降在允许的安全范围内,且与实际监测结果吻合,地下通道工程和周边建筑在开挖过程中是安全的。
The underground tunnel model is established on the basis of numerical analysis theory and the finite difference software FLAC3 Dis used to conduct simulation analyses on the excavation process.Whether the surrounding buildings are safe or not is analyzed based on numerical calculations and some safety measures adopted in the excavation process are put forward.The results of numerical calculations reflect that surface subsidence of the surrounding buildings is allowed by the law,identical to the monitoring data and so the underground tunnel engineering and the surrounding buildings will be safe in excavation.
