Based on the experimental study on Changjiang waterway slope cutting soil stabilization by HAS soil stabilizer and the experiment of soaking stabilized soil in the water and placing in outdoor,we analyze the influential factors of compressive strength at different time and conditions and proportion design of soil stabilizer,chips and soil,and obtain the changing rules and main influential factors of compressive strength of stabilized soil.The study results provide the technical basis for the utilization of Changjiang waterway slope cutting soil.
