Selection and Analysis of Improved Curing Agent for Drilling Slag of Bridge Pile Foundation Based on AHP
Improving solidification as roadbed filling is a better way to treat bridge pile foundation drilling slag.There are many types of solidi-fication agents that can be used for drilling slag improvement,such as cement,lime,fly ash,ion curing agents,organic polymer curing a-gents,etc.,each with its own advantages and disadvantages,making it difficult to choose.In response to this,the Analytic Hierarchy Process(AHP)is introduced for selection analysis,and a structural model for selecting drilling slag improvement curing agents is constructed and solved.Based on the calculation results,the suitability ranking of curing agents is determined.The results show that block quicklime is the most suitable improvement and solidification agent for drilling slag,followed by cement,fly ash,ion curing agent,and organic polymer curing agent.The selection results are objective and accurate,and the selection process and results have strong persuasiveness.
