Abstract

Abstract

Combined with a super high-rise complex project in Qingyang, Gansu, based on the monitoring data of piled-raft foundation settlement, the three-point method, modified hyperbolic method, Poisson curve method and creep settlement practical algorithm were used to predict the settlement of deep and thick loess foundation. The settlement of high-rise buildings on deep and thick loess foundation was predicted and compared with the measured data on a building site. The research showed that the modified hyperbolic method and the creep settlement practical algorithm were suitable for settlement prediction of super high-rise buildings on deep and thick loess foundation, and the latter could better predict settlement by existing limited measured data; the rationality of effective predict for the creep practical algorithm was verified and based on the settlement prediction about super high-rise buildings by the creep practical algorithm, the effective prediction range by the modified hyperbolic method was obtained according to existing measured data and allowable errors controlled less than 4 mm.
