Abstract : Tensile strength of snow was determined using indigenously developed automated centrifugal machine. Processed snow (sintered at -20 °C for 4 days) samples of dia: 65 mm and height:130 mm were tested using this machine.The experiments were conducted on sieved snow at four temperature levels of 0 °C, -3 °C, -6 °C and -9 °C at density ranging from 200-460 kg/m3. Results of these experiments have been compared with the earlier suggested models. Probability distribution of snow strength on the basis of current experimental data has also been presented. |
