The Mechanical Property of Bidirectional Geogrid and its Application Research in Retaining Wall Design

Abstract

Abstract: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 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.
