Research on Soft Foundation Treatment Scheme of Shiziyang Link Project
Soft foundation treatment is a very important technical problem in the field of highway construction,and the proper treatment is directly related to the quality of the project.The soft soil of the Shiziyang Link Project is widely distributed,and the control factors along the project are complicated,which makes the soft foundation treatment of the project very difficult.The factors such as subgrade fill height,stratum characteristics(including overburden characteristics,soft soil depth and thickness,physical and mechanical property indexes),subgrade stability and settlement control indexes,differential settlement,urban development constraints along the route,and green and low-carbon requirements etc.are taken into account comprehensively,and under the premise of ensuring quality,considering the application of economic and new materials and new technologies,single or combination treatment schemes such as surface solidification,drainage consolidation,composite foundation and light soil subgrade are adopted,and the concept of green highway is reflected.
