Settlement Control Research of Soft Soil Subgrade Based on Long Qi Bay Project ZHANG Xiang-donga, WANG Mengb, ZHANG Xue-leic Institute of Civil Engineering and Transportation ,Liaoning Technical University, Fuxin ,Liaoning, 123000,China azhxd2008@yahoo.com.cn, bwangmengnobel@163.com, czhangxueleill@163.com Keywords: Settlement control, Soft soil subgrade, Finite-element analysis, Settlement earth volume, Settlement forecast.
Soft subgrade settlement control and forecasting has become major technical problems of the soft soil subgrade engineering.
According to the engineering geological conditions, selected calculated depth is 22m, roadbed width is 30m, side slope is 1:1.
Conclusion As very different nature of the soft soil, there are different factors under different projects, the model presented in this paper still need to be tested by engineering practice and the model parameters need to be appropriately amended according to the different soil of different areas in different engineering application.
