Experimental and Numerical Investigations of the Influence of Reinforcement on the Load-Carrying Capacity of Ice Crossings

Resumo

Traditional methods used for the enhancement of the load-carrying capacity of ice crossings are not always efficient and the physicomechanical properties of the ice cover may strongly depend on the action of external factors. We present some results of the experimental and numerical investigations of the load-carrying capacity of ice samples, strengthened by longitudinal and transverse reinforcing bars. These investigations were carried out for different schemes of reinforcement. The experimental results were compared with the results of numerical analysis of the stress-strain state by using the ANSYS software complex and revealed their good agreement. We also estimated the efficiency of application of different schemes of reinforcement for the enhancement of the load-carrying capacity of ice cover.
