Abstract:
In this paper, we have studied the high strength geocell development technology route, analyzed the rules of the
tensile properties and creep properties of geocell, and established the relationship between elongation of stress and time, thus providing theoretical foundation for the development and engineering application of the new material. Through
theoretical analysis, experimental research and numerical simulation, the characteristics, raw materials and craftsmanship of the geocell have been studied. The research is given on its stress and deformation rules based on elongation test and
creep test. The rationality of the experiment is verified through numerical simulation and the conclusions are as follows: (1) With the research on the geocell traditional craftsmanship, combined with new technologies such as special ultrasonic
welding technology, intelligent optical fiber technology and fixed locking plate technology, a new-type of safety forewarning high strength geocell can be developed. (2) Based on the geocell material characteristics, the elongation test
and creep test are carried out and the tensile yield strength exceeds 250Mpa; the joint is welded by special crafts and the tensile strength ≥2000N/cm. (3) With FLAC 3D numerical simulation, simulation study is performed on the mechanical
properties of the new cell. Through analyzing the relationship between stress and strain, and time and displacement, the safety design and management construction of the new-type of geocell was proposed based on the actual situation of
simulation. (4) The innovation points of the new-type of geocell include: the optimization technique of whole tensile yield strength, fall proof technique of lock parts, and positioning and effective monitoring technique, which effectively solves
the geological problems of special projects such as ecological afforestation, sand fixation and high slope soft subgrade, and ensures the quality of the project and has high economic benefits.
