Abstract:
The settlement of the soft ground under embankment load after highway reconstruction is one of the main reasons that lead to related diseases of highway extension project. In order to accurately grasp the state of soft soil consolidation settlement and post-settlement value which can provide a basis and guidance to differential settlement control means for the design and dynamic construction, this paper established soft ground subsidence model which take into account creep, based on widened field settlement monitoring data by using three-layer BP neural network inverse model for calculating the material parameters, and on this basis, forecasted post-construction settlement of widening roadbed, compared with the actual monitoring results. The results show that the measured sedimentation value and the finite element method settlement value are basically consistent. 1 tab, 5 figs, 14 refs.
