In the urban construction, the number of ultra-deep excavation which is supported by underground continuous wall supporting system is increasing along with the use of many underground spaces. The covered back-digging combined with informational construction technology effectively control the deformation of underground continuous wall and excavation circumjacent environment. Based on the practical engineering field test data and three-dimensional numerical simulation calculation, we concluded variation pattern and relationship of the internal force and deformation which the large area long linear ultra deep excavation is constructed used the covered back-digging method.
