数值模拟计算在浅埋暗挖通道设计中的应用

Application of Numerical Simulation and Calculation in Design of Shallow-buried Excavated Channel

对数值模拟分析计算在浅埋暗挖地下通道设计中的应用进行了阐述,结合具体案例详细描述了在开挖施工方式、纵向拆撑长度控制等方面的数值模拟结果及分析应用。数值模拟计算完全能模拟常规地质条件下暗挖通道施工过程中的不同施工方式、工序带来的衬砌受力变化情况、路面沉降变化及相关建筑物、构筑物受影响状况。相关工程经验可供类似工程参考借鉴。

The application of numerical simulation analysis and calculation in the design of shallow-buried underground channel is expounded. Combined with the practical cases, the result, analysis and application of the numerical simulation are described in detail in the construction excavation mode and the longitudinal un-bracing length control. The numerical simulation and calculation can completely simulate the lining stress change, the pavement settlement change, and the influenced status of the relative buildings and structures caused by the different construction methods and procedures in the construction process of underground excavated channel under the conventional geological conditions. The relative engineering experience can be referred for the similar projects.
