【 摘 要 】

The soil sampling disturbance was inevitable in geotechnical engineering geological survey; it would change the engineering nature of the soil, and also affect the site geological record and indoor geotechnical test accuracy. This paper studied the relationship between the disturbance degree and the soil strength based on the reference of the new disturbance degree for the phenomenon of sampling disturbance and gave the expression for the disturbance degree and the soil strength. The strength of the disturbed soil sample could be reduced to the in situ strength according to the expression; it would have a certain practical significance.
