In order to study the effect of dynamic load and underground corrosive medium environment on mechanical properties of cemented soil, dynamic triaxial compression test is employed to obtain dynamic elastic modulus of cemented soil in different environment. The relationship curve on dynamic elastic modulus of cemented soil is analyzed in different environment. The results show that dynamic elastic modulus of cemented soil increases gradually with the increasing sodium sulfate corrosion solution concentration. When the concentration reached about 0.03mol/l, dynamic elastic modulus of cemented soil began to decrease gradually. When the concentration of sodium sulfate is small (less than 0.03mol/l), dynamic elastic modulus of cemented soil increased gradually. When the concentration of sodium sulfate is large (more than 0.03mol/l), the effect of corrosion and damage of cemented soil was produced by sodium sulfate solution and sodium chloride solution. And the corrosion effect of sodium sulfate solution is more than sodium chloride solution. Dynamic elastic modulus of cemented soil increases gradually with the increasing cemented content. Dynamic elastic modulus of cemented soil increases gradually with the increasing confining pressure.
