Optimization Analysis on Construction Methods of Single Arch and Large Span Subway Station in Upper-soft and Lower-hard Ground
摘要
Abstract
In order to adapt to the upper-soft and lower-hard ground and has economic benefits on the basis of construction safety, the arch cover method has been invented based on the PBA construction method by the tunnel workers. In this paper, based on the Guiyang metro line 2 Yangmingci subway station, with the threedimensional finite difference numerical simulation, the construction method of Yangmingci subway station has been analyzed and optimized based on the geological conditions and surrounding construction environment, considering the construction safety and time of construction and comprehensively comparing different working conditions. The basic idea of arch cover method has been discussed deeply and that the arch cover method should be applied to the special construction environment of the engineering area has been put forward.关键词
