Abstract: The existing supporting structures in Kunming are almost completed, but the planned ground anchors could not be installed. The semiinverse construction was applied to remediate this deep excavation project. Finite element analysis was performed to obtain the stress and strain in the supporting structures. Construction monitoring system was also installed. Based on the observed monitoring data, it is concluded that the semiinverse construction technique can effective reduce the construction duration.
