Stability Analysis of the Excavation Nearby Existing MTR Based on PLAXIS 3D
This paper aims at calculating the influence of foundation pit excavation on the stability of existing subway structure in the present sit-uation of the foundation pit excavation in the Metro operating protection area,combined with similar engineering experience comparison method(PLAXIS 3D),considering the joint action of soil and structure and the step construction process,analysed from the loading effect,unloading effect,transverse effect,longitudinal effect and spatial effect respectively.At the same time,the corresponding countermeasures are put for-ward.This method has great practical significance for the safety reserve of the construction process and guides the site construction meanwhile.
