盾构沿复杂线形穿越敏感建筑群安全风险控制研究

Research on Safety Risk Control of Shield Crossing Sensitive Buildings along Complex Linear

依托昆明市轨道交通1号线和5号线隧道工程采用盾构沿大纵坡、小半径复杂线性穿越云南省省委大院敏感建筑密集区,根据现场施工条件,分别从环境调查、信息化模拟、试验段推进、穿越段保护、注浆保护、监控量测和减振降噪等方面进行全方位、全过程安全风险的控制和研究,保证盾构施工安全可控,对既有建筑物和构筑物不发生有害影响。

In reation to the tunnel project of the Kunming rail transit Line 1 and Line 5,the shield is used to pass through sensitive buildings built-up areas of the compound of Yunnan Provincial Party Committee along large longitudinal slope and small radius complex linear.According to the site construction conditions,the all-round and whole-process safety risk control and research are carried out from environmental investigation,information simulation,test section promotion,crossing section protection,grouting protection,monitoring measurement,and vibration and noise reduction to ensure the shield construction is safe and controllable,and it does not have harmful effects on the existing buildings and structures.
