Abstrakt:

The introduction and rise of new geotechnical composite material greatly promote the development of civil engineering construction. Studying the mechanical properties of bidirectional geogrid and determining the reinforced soil retaining wall design calculation based on the friction reinforcement theory provide theoretical basis and research foundation for its application in the practical engineering. The mechanical properties of bidirectional geogrid are analyzed in depth through theoretical analysis, experimental research and numerical simulation. The mechanical property tests in light of different affecting factors are studied and the application of geogrid material in the reinforced soil retaining wall is simulated, thus yielding the conclusions as follows: (1) Study the mechanical properties in different temperature, loading and packing with the help of indoor pullout test and analyze the main factors affecting the mechanical properties of the geogrids in theory. (2) Analyze the reinforced soil retaining wall with friction reinforcement principle. Determine the calculation method of soil pressure and reinforcement and the check formula of the overall stability of the whole wall design and calculate the geogrid reinforced soil retaining wall in theory. (3) Simulate the bidirectional geogrid reinforced soil retaining wall with FLAC3Dand analyze the force of the retaining wall. Study the stress-strain curve according to the parameters of reinforced geogrid and retaining wall and analyze the overall force to guide the safety of the site construction. (4) Apply to the reinforced soil the retaining wall design. Thus the result is achieved that bidirectional geogrid is simple in construction, excellent in performance and economic in cost and has a good application prospect and social benefit.
