摘   要： 為實現固廢材料在戈壁土固化中的資源利用 ，選用工業礦渣粉和粉煤灰組成一種戈壁土固化摻合  料 ，加入堿激發劑激發活性 ，對其固化戈壁土的抗壓強度進行試驗研究 ，采用投影尋蹤回歸對試驗高維數據進  行分析 ，建立固化戈壁土抗壓強度 PPR 計算模型 ，驗證了模型的精度和穩定性 ，最后采用該模型進行仿真計算， 分析各影響因素與固化戈壁土抗壓強度的關系 。研究結果表明： 該 PPR 計算模型具有可靠性 ，各影響因子對抗  壓強度貢獻權重系數順序為： 固化劑摻量＞齡期＞粉煤灰摻量＞堿摻量； 仿真計算結果定量描述了各影響因素與固  化戈壁土抗壓強度的關系； PPR 模型較深入地挖掘了固化戈壁土抗壓強度高維數據的內在結構 ，為固廢材料固  化戈壁土的力學性能研究提供參考。

關鍵詞： 固廢材料； 固化戈壁土； 抗壓強度； PPR 模型

Abstract :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. 

Keywords : solid waste materials ; solidify gobi soil; compressive strength; PPR model
