| 摘 要： | 管棚法的设计多依赖于经验和工程类比,常用的设计理论多用于定性分析。数值模拟可以对管棚法设计进行量化分析。鉴于此,结合软土地区某浅埋地下通道工程,采用数值计算分析管棚和格栅在CRD法施工中的内力和弯矩,并提出针对危险工况采取相应的措施。

| Abstract: | The design of pipe roof method mostly depends on experience and engineering analogy,while the usual design theory is employed in the qualitative analysis.Numerical simulation can make quantitative analysis for pipe roof method.Thus,combining with a soft ground subway tunnel project,numerical calculation is adopted to analyze the internal forces and moments of pipe roof and grids in the CRD construction.Some measures against dangerous working conditions are taken. |
