Compressive Strength Calculation Model of Solid Waste Solidified Gobi Soil Based on PPR Modeling
In order to realize the resource utilization of solid waste material in the solidification of Gobi soil,industrial slag powder and fly ash were used to compose a solidifying admixture of Gobi soil,alkali activator was added to stimulate the activity,the compressive strength of solidified Gobi soil was tested and studied,projection pursuit regression was used to analyze the high-dimensional data,a PPR model for calculating compressive strength of solidified Gobi soil was established,the accuracy and stability of the model are verified,Finally,the model is used for simulation calculation,the relationship between the influencing factors and the compressive strength of solidified Gobi soil was analyzed.The results showed that the PPR calculation model is reliable,and the weight coefficients of each influence factor to compressive strength were ranked as the sequence of content of dosage of curing agent＞age＞flyash mixed＞dosage of alkali activator,the simulation results quantitatively describe the relationship between the influencing factors and the compressive strength of solidified Gobi soil;the PPR model excavates the inner structure of high-dimensional compressive strength data of solidified Gobi soil in depth,and provides a reference for the study of mechanical properties of solidified Gobi soil with solid waste materials.
