Abstract:Shenzhen Metro Line 5 passed through Jiu Wei Ling fault,which is one of the main faults of the northeast trerd at Shenzhen,there are multiple secondary faults and conjugate faults in the footwall of the main fault。The faults stability、the fault zone and the engineering geology and hydrogeological properties of the influence zone are the key factors for the selection and influence of the subway line。In this paper,the influence of the faults are analyzed in terms of its own stability,geostress,regional tectonic activity and the hydrologic characteristics of the faults zone on the Shenzhen Metro Line 5。It is provided that the fracture is stable,but rock masses break,joint fractures develop and permeability coefficient is large in the influence area,metro construction is liable to cause problems such as falling blocks,collapsing and water gushing,we should attach a great importance to it。This paper can be reference in similar engineering investigation and design。
