Research on Soft Foundation Treatment Technology in Road Embankment Engineering Construction
Soft soil is formed by sedimentation in aquatic environments,including peat,silty soil,and silt.It has the characteristics of high water content,large pores,low permeability,and weak shear resistance.Effective treatment of soft soil foundation can significantly improve the bearing capacity and stability of road subgrade,thereby effectively solving its settlement and instability problems.Given that soft foundation treatment accounts for a relatively high proportion of the total road cost,reaching 15%to 30%,how to reduce the cost of soft foundation treatment while ensuring the quality of the roadbed has become a research hotspot.This article takes the Zhoukou section of the Shangzhou Expressway as an example to explore in depth the comparison,optimization,and construction verification process of road soft foundation treatment design schemes.Through practical experience summary,the aim is to provide valuable references for similar projects,in order to achieve cost optimization and reduction while ensuring the quality of the roadbed.
