    • Abstract
  • Based on the British GDS dynamic triaxial test instrument, the triaxial dynamic load tests on subgrade saline soil in western areas of Qinghai Province are performed. Under temperature change, the variation laws of parameters of dynamic stress of failure, dynamic cohesion and dynamic internal friction angle with confining pressure and frequency are discussed. The destructive dynamic stress-confining pressure-temperature relational surface at different dynamic load frequencies is established, and the equation for fitting the surface with temperature is obtained. The test results show that the temperature change is extremely sensitive to the cementation of soil-ice-salt, and with the decrease of temperature, the destructive dynamic stress of saline soil obviously increases. The dynamic cohesion and internal friction angle increase with the decrease of temperature.
