摘要
///Based on a lot of in-situ dynamic triaxial tests,the paper research the relationship of dynamic stress, dynamic strain, dynamic modulus of elasticity and damping ratio to the moisture content, temperature, confining pressure, dynamic stress level and frequency of frozen aeolian soil in west of Liaoning Province under earthquake load. 18 group of tests were conducted by adopt three level six factors design method. The tests results show that with dynamic stress amplitude increase and temperature rise, the dynamic deformation will increasing in the same level of vibration numbers. Dynamic shear strength increasing with confining pressure increasing in the same temperature. The dynamic stress and dynamic modulus of elasticity of low-temperature frozen soil are superior than high-temperature frozen soil. The dynamic damping ratio decrease with deformation and frequency increasing,increasing with moisture content increasing. The results provide reliable aseismic design references to construction engineering in frozen aeolian soil area.
