- Abstract
The excavation of city subway pit breaking the original balance of the soil, affecting the safety of existed buildings and the surface subsidence of construction are important and direct factors which react to construction impacts. Using the Gray Relational Analysis Theory, through monitoring measured data of factors, building gray correlation analysis among excavation of subway construction surface subsidence, horizontal displacement of pile top, deep displacement, the groundwater level, the support axial force, the anchor cable tension and other factors, get the collective degree of different monitoring program. The results show that, the factors, from maximal to minimum correlation degree, which affect surface subsidence includes horizontal displacement of pile top, anchor cable tension, the groundwater level, deep displacement, strut axial forces. It provides a theoretical basis for law of surface subsidence and similar monitoring program optimization for the future projects.
