To validate the stabilization effect of stabilizing agent GX08 treating the marine and lacustrine soft soil in Hangzhou

and to investigate the adverse influence of organic matter on cementing soft soil

unconfined compressive strength (UCS) tests are performed on stabilized soils. Test results indicate that organic matter significantly hinder the growth of the strength of stabilized soil

whereas stabilizing agent GX08 can effectively enhance the strength of the stabilized soil. The results show that the strength of stabilized soil is well correlated with organic matter content as a form of quadratic function

and it is correlated linearly with cement content

and both are correlated as the form of logarithmic function with stabilizing agent GX08 content and curing time. The total cement/water is applied to the establishment of the stabilized soil strength model. Based on the analysis of tests data

a predict model

considering the influences of organic matter content

cement content

stabilizing agent content and curing time on the strength of stabilized soil

is proposed to predict strength development. Finally

the model is to be promoted to use

so as to verify the applicability of the model.
