Soft Foundation Treatment Technology in the Design Process of Highway Subgrade Pavement
In the design of highway subgrade pavement,soft foundation is a very difficult problem,usually soft foundation will cause a series of problems such as settlement and deformation of highway subgrade pavement,and even lead to cracks and pavement collapse,which seriously affects the normal use of highway.Therefore,effective-ly dealing with the problem of soft foundation is the key to the pavement design of highway subgrade.Taking the construction project of Yinchuan-Xiaoguan secondary highway in Jishishan County as an example,this paper ana-lyzes the soft foundation hazards and problem treatment methods of this section of the pavement,and proposes several soft foundation treatment technologies,including backfill soft foundation treatment technology,strong compaction method,deep cement mixing pile treatment,lightweight soil embankment filling technology and sur-face drainage soft foundation treatment technology.Finally,according to the design of highway subgrade pave-ment,the corresponding soft foundation treatment technology is selected,in order to provide a reference for do-mestic highway engineering construction.
