【Abstract】 Based on the engineering geological analysis of the shaft frame inclination causes,ANSYS finite element method was used to simulate and forcast the stress,deformation and strength variation law of the shaft frame and main supporters under various subsidence conditions of the inclined leg foundation.It was suggested to use the method and technology of wall back grouting and steel cement pipe reinforced concrete piles for the foundation treatment.The execution of the controlled inclination rectification of shaft frame under the guidance of numerical simulated forcast and on site safety monitoring is described.更多还原
