In order to ensure the reinforcement of the Kuahuqiao canoe site, field test experiments were done, namely by applying modified water epoxy and ethylsilicate agent separately to small areas of concealed parts of the site. Results were evaluated by measurement of density, color change, pH value and strength of the treated parts. These experiments showed that the soil sample treated with the modified water epoxy showed excellent in reinforcement effects, resulting in higher density and shear strength without pH or color change.
