Prediction method for content of cement in soil at different depths in solidified mixing pile

The invention discloses a method for predicting the content of cement in soil at different depths in a solidified mixing pile, and relates to the technical field of soft foundation reinforcement. The prediction method comprises the following steps: preparing a soil cementing material; mixing the soil cementing material with the to-be-solidified soil according to a plurality of different preset proportions, and solidifying to obtain a plurality of pieces of solidified soil; measuring the content of ettringite in the solidified soil; constructing a function relationship between the ettringite content and the soil cementing material proportion; sampling is conducted on the solidified stirring pile at different depths; measuring the content of ettringite in the sample, and calculating the content of soil cementing materials at different depths in the solidified stirring pile according to the constructed function relationship; wherein the soil cementing material comprises the following components in parts by weigh
