Application of Retaining Wall-frame Structure in High Fill Road Engineering
In order to avoid the road subgrade slope encroaching on the basic farmland on both sides and reduce the bearing capacity of subgrade soil,from the perspective of structural safety,rationality,economy and construction convenience,this paper compares with the scheme of bridge and buttress retaining wall,puts forward a combined structure of cantilever retaining wall and closed frame,and analyzes the stress and engineering feasibility of the structure,which has been successfully applied in practical projects.The results show that this kind of structure can avoid road encroachment on basic farmland,the construction speed is fast,can reserve space for municipal pipelines,and has the advantages of saving project cost,which can be used as a reference for similar projects.
