层次分析法在东引运河虎门河段堤岸整治工程设计方案优化中的应用

Application of AHP to Scheme Design of the Embankment Renovation Project of Humen River Section of Dongyin Canal

在东引运河虎门河段堤岸整治工程中,通过对不同堤岸情况进行分析比选,采用直墙式和直斜复合式断面型式,以及U型预应力板桩和砼灌注桩,并应用运筹学中的分析法优化河堤地基处理施工方法,选取水泥搅拌桩的地基作为最优处理方式,因地制宜、节约成本、缩短工期,在绿化美化河岸的同时,更好地优化了整治效果。

In the embankment regulation project of Humen reach of the East Diversion Canal,through the analysis and comparison of different embankment conditions,the vertical wall type and the straight inclined composite section type are adopted,the U-shaped prestressing sheet pile and concrete cast-in-place pile are applied,and the analysis method in operational research is applied to optimize the embankment foundation treatment construction method,and the cement mixing pile foundation is selected as the optimal treatment method,which is suitable to local conditions and convenient for construction.As a result,better effect of the regulation project is achieved with cost reduced,construction period shortened,riverbank ecological system protected.
