Abstract


The middle and lower reaches of the Yellow River alluvial plain construction of highway , short duration , high embankment , settlement control of the key technical issues that must be addressed . Lead engineering , State Road 205 line Binzhou Yellow River Highway Bridge filling roadbed rely on DJM pile combined with geogrid reinforcement technical processing high embankment foundation , based on field trials , analysis of stress and settlement of the Joint reinforcement area subgrade the deformation law reveals the reinforcement mechanism of the joint disposal technology , provides a reliable technical support for the design and construction ; simulation test technology, geogrid interface stress distribution and geogrid layers , buried layer between the thickness of the reinforcement effect ; triaxial test to study the feasibility of reinforced composite soil equivalent circumference pressure method theory ; FLAC - 3D software for different operating conditions of the numerical analysis , and the underlying layer of additional stress field and the the Boussinesq solution calculation results were compared ; Finally, improved stability calculation method were analyzed the geogrid improve the stability of the embankment . Good research guide the design and construction of a high fill ground Binzhou Yellow River Highway Bridge lead engineering , design and construction of road embankment on soft soil area also has important theoretical significance and practical value .
