In order to study the dynamic deformation characteristics of clay stabilized by lime-lignin, a set of resonant column test was carried out on the stabilized clay with different confining pressures and lime-lignin contents, and the development law of dynamic shear modulus was analyzed. The results show that the maximum dynamic shear modulus and dynamic shear modulus ratio of clay stabilized by lime-lignin increase with the increasing of confining pressure. The maximum dynamic shear modulus and dynamic shear modulus ratio of 4%lime +4%lignin stabilized clay are the highest. Under a confining pressure of 300kPa, the maximum dynamic shear modulus of 4% lime+4% lignin stabilized clay is 17.3% higher than that of 8% lime stabilized clay and 185.4% higher than that of pure clay. Based on the shear strength parameters, the relative structure of stabilized clay was calculated and the relative structure of 4%lime +4%lignin stabilized clay is the highest. On the basis of Hardin formula, a characterization model of maximum shear modulus was established by introducing relative structural. The model has good accuracy and can provide a theoretical basis for evaluating the shear modulus characteristics of clay stabilized by lime-lignin.
