NumericalPrediction of High-rise Building Settlement Based on Monitoring Data
In this paper,the settlement analysis of two high-rise buildings based on finite element modeling is presented.An improved subplas-tic model with intergranular strain concept is used to predict the settlement values at different stages and compare them with the actual scale geotechnical monitoring(GTM)data obtained from the deformation meter installed in the borehole below the foundation.The results show that the subplastic model is used to predict the settlement of high-rise buildings in Neogene clay,and the mR Value and r parameter jointly affect the predicted deformation of high-rise buildings during excavation,construction and operation,while βr only affects the deformation during ex-cavation and construction.In general,the deformation predicted by the subplastic model at the excavation stage and the short-term consolida-tion stage is close to GTM,while the deformation at the long-term consolidation stage is sensitive to the contact load σol.
