COMPRESSIVE DEFORMATION ANALYSIS ON NEW PLATE AND AIRBAG COMPOSITE STRUCTURES

WANG Guang-zheng;LI Zhi-gang;College of Field Engineering, PLA University of Science & Technology;  
Under the condition of reality demand of traffic emergency rescue and traffic engineering security against future disasters, a pavement channel equipment composed of airbag and deck bearing plate capsule combination structure is developed. On the basis of analyzing the superiority of airbag bearing structure, a theoretical calculation model is established and the compressive deformation of the proposed structure using the finite element is analyzed. Through pressure tests, the deformation of the composite structure under actual load condition is verified. The experiment proved that this kind of structure conforms to the requirements of the design load and deformation. The structure can meet the needs of the traffic emergency rescue and disaster relief.
