Abstract
Characterized by bigger section and shallower coverage, the mined metro station often collapses during construction, and the longitudinal length influenced is as long as dozens of meters. To improve the safety of subsequent construction, this paper studies the construction after collapse based on collapse cases and with risk analysis, finite element algorithm and data of site monitoring and measurement The study results show that double side-wall pilot tunnel method is safe and reliable in the post-collapse construction. Furthermore, the method of“dividing large span into smaller ones” proves to be effective to control the deformation during subsequent construction. It is also demonstrated that the subsequent construction risk can be effectively reduced with multiple measures in terms of construction methods, support systems and construction techniques; the physical properties of rock, as well as the bearing capacity of support systems and surrounding rock are improved.关键词
