Comparison of Deformation Characteristics and Common Treatment Methods of Soft Soil Foundation in First-class Highway Widening
In the infrastructure construction,the construction of the first-class highway widening engineering is to cope with the increase of traffic flow and improve the road capacity.In order to solve the problem of subgrade deformation of soft soil foundation in the widening engineering of first-class highway,this paper studies the deformation characteristics of soft soil foundation in the widening engineering of first-class highway,and compares the effects of two common treatment methods of plastic drainage plate and granular pile.By analyzing the actual case,collecting field data,determining the treatment test scheme of plastic drainage plate and granular pile,and comparing and analyzing the test results,it is verified that the use of plastic drainage plate has more advantages than granular pile.
