Geocell-reinforced soil pavement and the finite element analysis of mechanical


	response

Abstract

Abstract:

To investigate the reinforcement effect and its mechanical response law of geocell-reinforced soil pavement, this

study selected the geocell-reinforcement material of Germany Novus. The effect of strengthening soil pavement

with geocell was tested by testing the resilient modulus of the pavement through the bearing plate experiment.

Firstly, using the finite element simulation method, a finite element analysis model for the mechanical response of

the geocell-reinforced soil pavement was established and validated. Secondly, by selecting typical aircraft load

effects and structural parameters of the geocell-reinforced pavement, the mechanical response sensitivity and

mechanical response law of the geocell-reinforced soil pavement were analyzed using the maximum vertical compressive strain, maximum vertical displacement, and depth of the roadbed working area as analysis indicators.

The results demonstrate that under 90% compaction degree, the resilient modulus of the geocell-reinforced soil

pavement increased by 23.7%. The subgrade resilient modulus has the most significant impact on the maximum

vertical compressive strain and maximum vertical displacement of the structure of geocell-reinforced soil pavement. The maximum vertical compressive strain decreased with increasing subgrade resilient modulus, geocell elastic modulus and thickness, but increased with increasing geocell cutout size. The maximum vertical displacement of the pavement is closely related to the weight of a single wheel of the aircraft main landing gear, and heavier aircraft will increase the maximum vertical displacement. The parameters of the pavement structure have no significant effect on the depth of the roadbed working area, and there is a linear positive correlation between the depth of the roadbed working area and the weight of a single aircraft main landing gear. This study can provide

reference for the design and development of geocell-reinforced soil pavement.
