Lateral variations of the karst of deep buried tunnel engineering is big. The heterogeneity of it is strong. The tunnel is combined with Changsha Rail Transit Line 2 at one section of the first phase construction. Under the urban environmental conditions, it is considered to use auxiliary seismic wave imaging method assistanting with Rayleigh surface wave method. It is the detection and prediction method of comprehensive geological analysis of karst hazard, which identified the underground targets of deep buried tunnel effectively. To avoid a single technique multiple solutions, it can reflect the complexity of karst formations geological features objectively. Therefore, it can reduce the risk of drilling and take appropriate treatment measures to provide adequate and reliable basis. |
