Abstract: Most natural soft soils have structural characteristic; so the disturbance of foundation treatment changes engineering property of soft clay ground. Mechanical parameters of disturbed soft ground cannot be measured accurately by laboratory experiment. In order to obtain calculation parameters of disturbed soft clay ground, based on in-situ test and column-expand theory, quantitative calculation methods of disturbance degree of structured soft clay ground resulted from foundation treatment are presented. The examples show that the structured soft clay ground disturbance degree resulted from the setting of PVD is about 30 %; it can be used to calculate settlement and stability of disturbed soft clay ground.

Key words: structural characteristic, soft clay, foundation treatment, disturbance degree
