【Abstract】 After a series of experiments relied on the independent invention foaming agent,the paper studied the stability and froth ratio of the foam and found out evaluate to efficiency of foaming agent.After the experiments on clay and sand soil,the paper acquired the change rule of the permeability.The tests show that the modifying result of foaming agents is remarkable and provides experimental conclusion for research on foaming agents modifying the complex soil in shield tunneling engineering.更多还原
