1 概述大治河西闸枢纽工程位于闵行区浦江镇鲁汇闸港,西距黄浦江约1公里,主要由1座六孔节制闸、1座套闸和1座公路桥组成,是三级中型水工建筑物,也是上海市目前最大的中型水利枢纽工程之一。近10年来,西闸套闸的船舶通航流量以每年20%-70%的幅度递增,2002年实际通航流量达到了2300万t.远远超过其1200万t.的设计通航流量;此外,通航船舶中最大的已逾千t.而西闸的设计标准为300t.级,砼结构翼墙受大量的、大吨位过闸船舶的擦碰、撞击较多,加之日久碳化,导致露筋严重,影响结构牢度。
1 Overview Dazhihe West Gate Project is located in Luhuizhaigang, Pujiang Town, Minhang District, about 1 km away from the Huangpu River. It is composed of a six-hole control gate, a set of gates and a highway bridge. It is a medium-sized water It is also one of the largest medium-sized water conservancy projects in Shanghai. In the past 10 years, the navigation flow of the West Gate has been increasing by 20% -70% annually, and the actual traffic volume reached 23 million tons in 2002, far exceeding the designed traffic flow of 12 million tons. In addition, The largest ship has more than 1000. And the West Gate design standards for the 300t. Level, concrete structure wing wall by a large number of large tonnage ship gate collision, more impact, combined with the long carbonization, resulting in serious tendons , Affect the structure fastness.
