Abstract: Aiming at the complex and random characteristics of foundation settlement mechanism, an improved MMF settlement prediction model based on Markov chain theory is established. Firstly, the MMF model is fitted by CurveExpert software with some measured data. Then, according to the relative error predicted by the MMF model, the state interval is divided according to Markov theory, and the probability matrix of state transition is constructed to predict the state of the next settlement, thus the MMF prediction value improved based on Markov chain is obtained. Finally, the model is applied to the settlement prediction of shenzhen Binhai road municipal engineering soft soil subgrade, and the prediction accuracy of the model is analyzed. The results show that the prediction accuracy of the MMF model based on Markov chain is significantly higher than the MMF model. The modeling method is reasonable and can be used for similar engineering prediction.
