Abstract

The deep mixing method is a commonly used foundation treatment technology for marine soft soil sites. Due to the long-term corrosion of seawater ions, the deterioration of cement soil pile in-site is inevitable. Revealing and predicting the development trend of cement soil can provide data support for the durability evaluation of marine engineering. The existing research on the deterioration development trend of cement soil neglects the influence of different stress states along the length direction of the pile on the deterioration. This study developed a tester that can simulate the deterioration of solidified soil in the stress state of natural foundations. A rapid prediction method for the deterioration depth of cement soil considering the influence of seawater pressure is established. The research concept has certain reference significance for research on the prediction of the deterioration depth for solidified soil in similar corrosive environments.
