Over-deformation Method and Its Application in Deep Excavation

Based on over-deformation rule, a new method to determine the stabilization of pit, over-deformation method, is established. It becomes facility to calculate the critical guideline of the deformation of the pit. Regarding it as the precaution guideline, we can directly evaluate the stabilization of the pit. Finally, it is applied in the evaluation of the RunYang Bridge deep pit's stabilization and it is proved more efficient than other method.
