穗莞深城际下穿深中通道变形规律及控制技术研究

Research on the Deformation Regularity and Control Technology of the Shenzhen-Zhongshan Passage in the Guangzhou-Dongguan-Shenzhen Intercity

结合穗莞深城际轨道交通盾构隧道下穿深中通道工程背景,采用有限元软件MIDAS/GTS数值模拟,对盾构隧道下穿深中通道施工过程进行分析,研究了深中通道主线敞开段结构及敞开段下桩基的变形规律,提出了相应施工建议和控制标准,为类似下穿工程提供了指导和参考。

Based on the engineering background of the Shenzhen-Zhongshan passage tunnel under the Guangzhou-Dongguan-Shenzhen intercity rail transit shield tunnel,the finite element software MIDAS/GTS numerical simulation is used to analyze the construction process of the construction process of the shield-passage tunnel through the Shenzhen-Zhongshan passage tunnel.The structure of the open section of the main line and the deformation law of the pile foundation under the open section provide corresponding construction recommendations and control standards,which provide guidance and reference for similar underpass projects.
