马安围平马围合围土坝的树型失稳模型及AHP安全评价方法

The Dam Safety Evaluation Method of Stability Loss Model and AHP in Maanwei Pingmawei Hewei

对马安围平马围合围的土坝进行稳定性检查,根据检查结果,建立土坝失稳的树型模型,其为一个包含两个子级模型的三级模型,从结构和渗流角度对该模型进行了构建,并对所构建的"树型"失稳模型进行AHP分析。基于此,提出一种量化的安全值评价法,同时结合马安围平马围合围的工程实例,得出土坝失稳的防范重点指标与量化安全值,为有针对性地进行水利建设与管理作指导。

The Maanwei Pinganwei Hewei encircled the stability check, according to the inspection results, a dam lost tree model of stability is proposed, which is a model consists of two sub grade three level model, the construction of the model from the structure and flow angle, and the construc- tion of the ＂tree＂ instability model AHP analysis, based on this, the safety value of a quantitative evaluation method is put forward , combined with an engineering example, the dam instability pre- vention index and quantify the safety value, which is as a guide for water conservancy construction and management.
