【Abstract】 In consideration of the fact that the method commonly used for stability evaluation of foundation pits cannot fully reflect the stability of foundation pits, the interference-energy theory is introduced, and an interference-energy method for stability evaluation of foundation pits is proposed. The present method can give an overall evaluation of the stability of the integral and local structure of foundation pits from the angle of energy. As an example, the present method is applied to stability analysis of the south anchor deep foundation pit of the Runyang Bridge during its excavation process, and the process of evaluation is introduced.更多还原
