Research on Prediction and Analysis Methods of Settlement Due to Preloading of Soft Ground Under Coastal Highway Embankments
This paper studies the prediction and analysis method of preloading settlement of soft foundation under embankment load for coastal highways,taking a coastal highway in Pingtan,Fujian Province as an example.By selecting settlement data with different time start points and time intervals,the final settlement and consolidation degree are calculated using the hyperbolic method and the three-point method,and the calculation results are compared and analyzed.The results show that both the hyperbolic method and the three-point method can effectively predict settlement.Selecting appropriate time start points and equal time intervals can improve the accuracy of the calculation results.Moreo-ver,human operation has a significant impact on this process.In practical applications,the hyperbolic method is relatively conservative,which is beneficial for the full consolidation of soft soil foundation and the improvement of engineering quality.On the other hand,the three-point method is conducive to shortening the construction period and saving costs.Therefore,in engineering practice,appropriate methods should be selected according to specific requirements.
