    • Abstract
  • Yujiabu group excavations cover a huge plan area and meet the problem of interaction among various projects. Different excavation sequences of the group excavations are simulated by means of 3D numerical model. The results show that the superimposed ground settlement occurs among the nearby excavations caused by their excavation, and the distribution of support axial stress is influenced. Some suggestions for excavation sequence and support system and construction control measures are proposed according to the calculated results and analyses.
