基于层次分析法的土石坝灌浆防渗体安全性评价体系研究

Study on Grouting in Embankment Dam Seepage Safety Evaluation Based on the Analytic Hierarchy Process

帷幕灌浆是病险土石坝防渗加固中较为主要的方法,其属于地下隐蔽工程,其安全性或耐久性是病险土石坝得以正常运行的保证。基于层次分析法,通过模型及评价体系的建立、权重及隶属度的确定,结合实际工程,提出了一种病险土石坝帷幕灌浆防渗体安全性评价的方法,对土石坝防渗加固体的安全性或耐久性评价提供参考。

Curtain grouting is a more significant seepage method in the ous embankment dam, for it belongs to the underground and concealed ables to guarantee the normal operation of dangerous embankment dams. reinforcement of the danger-work , its safety or durability Based on the analytic hierar-chy process, through the establishment of the model and evaluation system, the determine of weights and the degree of membership, combine with practical engineering, we offer the safety evaluation of a dangerous embankment dam curtain grouting body, providing a reference to the safety or durability e-valuation of embankment dam seepage reinforcement.
