Abstract:Soil disturbance degree(SD) defined by Z. Hong and K. Onitsuka is used to analyze the relationship between SD and parameters of soil strength;and the function with the soil strength,disturbance degree and soil sensitivity are established. It is found that the soil yield stress of high sensitivity soil changes greatly when disturbance obeys to the function. Then,the relationships between the soil shear strength,tip resistance of CPT,confined modulus and soil disturbance are discussed. At last,the laboratory vibrating model tests are carried out to simulate soil disturbance;and samples with different vibrating times are performed with different disturbance degrees. After vibrating,odometer tests and unconfined compression tests are performed;and reliability and reasonability of the function and relationship are validated.
