ROAD CONSOLIDATION AND REPLACEMENT COMPOSITE FOUNDATION TREATMENT AND REINFORCEMENT CONSTRUCTION TECHNOLOGY
Based on the situation of road construction site foundation,this paper puts forward the road consolidation and replacement composite foundation treatment and reinforcement construction technology,that is to use cement mixing pile combined with aggregate replacement and filling method,at the same time,using the finite element software Midas GTS NX and BIM technology,different depth of mixing pile and different thickness of skeleton replacement are proposed.In order to overcome the problem of insufficient subgrade bearing capacity caused by the continuous variation of geological thickness and stratum parameters along the road,the aim is to reduce the construction cost on the premise that the bearing capacity of foundation treated by this technology can meet the requirements of design and relevant codes.
