Research on the Application of Water-Soil Combined Surcharge Preloading Technology for Highway Soft Subgrade
Water-soil combined surcharge preloading technology is a typical technology used in the disposal of soft subgrade in highway engineering.The application of water-soil combined surcharge preloading technology allows the acceleration of the settlement of the filling subgrade,reduction of the uneven settlement caused by construction,effective improvement of the construction quality of the subgrade,and the enhancement of the stability of the subgrade of the whole highway project.The conventional earth-rock preloading technology involves a large amount of earthwork,which has a great impact on the ecological environment.At the same time,the construction cost is high,and the demand for earthwork in the region is enormous.Taking the soft subgrade treatment of a highway project in Xinjiang as a case study,aiming at the shortcomings of the traditional earth-rock piled soft subgrade section,the water-soil combined surcharge preloading technology was proposed and applied.At the same time,the construction effect of the water-soil combined surcharge preloading technology was analyzed.The analysis results confirm the feasibility of the water-soil combined surcharge preloading technology and its effectiveness in securing the safety and stability of the roadbed,thus promoting a reference for future similar highway soft roadbed treatment projects.
