Study on the Impact of the building cracking as the deep foundation pit excavated in the Airport Road of Xiamen

Abstract：Based on monitoring data analysis.A detailed analysis is done on the excavation of deep foundation pit impacts on mechanism of the building cracking, deformation control of the cracks and building's deformation control by the combination of theoretical analysis and numerical analysis method in the Airport Road of Xiamen.Some appropriate restoration and strengthening foundation schemes are put forward.The assessment conclusions of the building long-term stability are studied when the scheme is under proceeding.It offers references for the restoration work of building after the follow-up mining tunnel passed from bottom of the 95 buildings.
