航道改建工程中护岸结构形式优选

航道改建工程中,常因航道两岸环境复杂,须对护岸结构进行多方案的比选。而比选大多以定性分析的主观判断为主,往往存在一定局限性。以上海某航道综合整治工程一标段护岸结构的优选为例,针对典型段护岸,运用灰色关联层次分析法从中寻求安全可靠且经济合理的护岸结构方案。针对特殊段护岸,分析通常遇到的特殊环境条件情况,找出技术可行的较理想的护岸结构方案。研究成果可为类似工程提供借鉴。

Optimal selection of revetment structure in waterway reconstruction engineering

In the waterway reconstruction engineering,it is often necessary to compare and select multiple schemes for the revetment structure because of the complex environment on both sides of the waterway.However,most of the comparison and selection are based on the subjective judgment of qualitative analysis,which often has some limitations.Taking the optimization of the revetment structure of the first section of a comprehensive regulation project of a waterway in Shanghai as an example,aiming at the typical section of revetment,this paper uses the grey relation analytic hierarchy process to seek a safe,reliable and economic reasonable revetment structure scheme.In view of the special section of revetment,the paper analyzes the special environmental conditions commonly encountered,and finds out the technically feasible and ideal revetment structure scheme.The results of this paper can be used in similar projects.
